Okay I'm still not quite understanding then...
I'm standing at point X, with a goblin beside me. Ten feet away, at point Y, there is another goblin. Twenty feet past that, at point Z, there is a third goblin.
I am a fighter, and I have 3 attacks because I'm 11th level - I want to hit each of these goblins once, in *one* turn. Let's imagine I rolled good initiative and am on top of the order.
A: Initiative is rolled and bonuses applied. Combat order is determiner.
Okay, with you so far. I'm first in the order here, so, it's my turn... right?
B: Players and opponents are grouped into movement phases based on initiative roll( up to 10 phases total). A movement bracket is shown above pictures in upper left. Movement Phase may be empty allowing for everyone to move without any combat occurring before the next movement phase.
Er... maybe not then. We're breaking the first turn into a handful of 'phases', where
everyone does things
each phase, more like a card game? Only, maybe not that either, since it seems like maybe different people are in different movement phases based on their initiative... so, maybe me and one goblin are in the '1st' movement phase, and the second goblin is in the 4th movement phase, and the third goblin in in the 9th movement phase? Like that? This feels overly complicated already... but continuing...
C: Movement phase takes place. Movement action points are restored. Everyone may do one of the following:
1 Move to your maximum for this phase.
2 Move up to 1/3 of your movement and use a movement action, movement/bonus action or a movement/action.
Okay, so, I'm up... I can choose to move my full 30 feet (don't want to do that), I can choose to move no more than 10 feet and take a "movement action" (which is not movement, and also not a standard action, but rather something new being the specific actions that are allowed to occur in movement phase?); I don't think I want to do that - I want to hit the goblin that's right in front of me.... but I don't think I can in this 'phase'. I know I've got a 'combat phase' coming up, so for now I guess I stand firm? Or maybe chase on this goblin in front of me in case it moves? Feels counter-intuitive that it is probably going to move away before I can try to attack it at all, even though I rolled higher initiative than it... that feels pretty, well, I'm sorry, but that feels pretty silly, at this point... no offence intended, it's just strange.
D: After player makes all movement decisions choose end movement turn and all movement starts.
So, I input chase, in case the goblin moves. The goblin decides to run its full 30 feet away... and my character, I guess, uses all 30 feet of her movement to chase after it... that isn't what I wanted her to do at all.
Scratch that, then... I input stand firm. The goblin runs away - now (I assume) I have to decide between whether to use my reaction to hit the goblin I wanted to hit with my normal attacks, or to let it go and keep my reaction for shield (I'm an eldritch knight fighter after all). this is not a tactically good situation I've been put in; I can't direct my own abilities the way I want to, it feels.
E: Combat phase takes place for those whose initiative falls on this phase. Action points and bonus action points are restored. During this phase they may do one of the following:
1 Choose a non movement action and a bonus action.
2 Defer combat to a later movement phase.
Action and bonus action points are restored. unless you already used them in the first movement phase - which seemed to imply that doing so would not see them restored until the next combat round, and we're still in the first... so... if this were the
Second combat turn, we wouldn't have had any action or bonus actions to spend in that first phase at all, since we would have used them last turn and they aren't restored until now., unless I'm misunderstanding your meaning here. And, if we did have action and bonus actions to use in the movement phase before this phase on this turn, and used them.. then they wouldn't restore now anyway, because using them there implied that they wouldn't come back until next round. Okay, this is confusing.
So, does this combat phase happen after the FIRST movement phase... or does it happen after the LAST movement phase, or does
A combat phase happen after EVERY movement phase?
Regardless... I didn't move, because I didn't want to use the chase command to use up all of my movement instantly... but I had to let that goblin run away, since I wanted to keep my reaction. Now I have no goblins next to me and its the combat phase. It seems like I cannot move, unless I use my action to Dash (despite my still having 30 feet of my movement left, unused); I cannot attack anything, and have no choice but to defer my combat phase until later, apparently, because I need to be in range of a goblin to hit it with my sword and I'm not.
F: After player makes all combat decisions choose end combat turn and all combat starts (players and opponent may share simultaneous attacks).
So, how this feels right now is that, I rolled top of initiative, and despite that, I've functionally had to skip my turn while other creatures have acted all around me - that goblin who rolled below me initiative, but close enough to still be in my movement section has now turned and fired a bow at me, while I, with the better initiative have been unable to actually attack anything.
It also seems like we've got some ridiculous Achilles and tortoise situation going on where someone can input chase and someone can input avoid, and so they skitter down the movement phases until they've both run out of movement with neither of them managing to make any melee attacks because the timing is literally always wrong for it. A single turn would take forever, like this, or so it seems.
==
Let's suppose that the first goblin didn't move, because it intended to attack me. Okay, great... NOW when the first combat phase comes up, there's a goblin close to me, so I attack it. I have two more attacks, but the goblin is dead. What happens? How do I move to and target attack on those other two goblins before the end of this 1st turn, which feels like it's going on for a dozen mini-turns already? It sounds like what you may actually want is a real-time combat game, given the way you've mapped some of this out and the things you've emphasises.
Sorry if this seems overly critical, but what you've set up feels excessively, needlessly complicated and convoluted, would likely be confusing to new players, feels counter-intuitive in several aspects, and ultimately seems to actually ROB players of tactical flexibility because it extrapolates intention out of the players hands in ways they may not want (such as chasing that goblin that ran off for all of my movement, which I only wanted to use some of at most). You still have initiative, but initiative seems largely pointless when you get right down to the actual play mechanics, and simultaneous action has, itself, a whole host of other issues that don't mesh well with an individual turn-based system.
It sounds like you might want to design your own new system for a tactical game, that plays by its own set of rules, and it might be really neat and fun to play - but it won't be D&D, or anything resembling it by that point. If I've misunderstood how this is meant to work, then all I can say is take that as a comment in and of itself. Best of luck refining your idea ^.^
