I don't understand the UI layout for cancelling Concentration spells at all.
The button to cancel these spells displays directly under the large round portrait, with a tiny icon at the far left of the hotbar. Problem is that the "End turn" button is on the complete opposite side of the screen, at the far right of the hotbar. The group/ungroup all button is also on the far left of the screen, whereas my cursor is typically just coming off a hotbar spell/action icon or the end turn roundel or the button to enter/exit TB mode all over towards the righthand side.
If I need to quickly select a character to cancel a spell like Wall of Fire this is frustrating, cause first I need to stick that initial selection to get the full hotbar to display for that character. For example, say you have the summoned Woodland Being cast Spike growth, but if you also got a couple elementals or skeletons she's maybe sandwiched between like 5 portraits increasing the chance you click the wrong thing. The problem could be mitigated by ungrouping automatically and remaining in turn based mode when combat concludes, but don't have a setting like that in the options.
I dislike the chain movement scheme. Ungroup/Group all is inconvenient. Generally what I want is a 3-1 comp or a 2-2 comp. If there were leadership positions, then we could have the leader for group A, leader for B and maybe key off that, but under the current scheme it's pretty rough. Camp management for switching characters and buffing dailies is very click/time intensive. Pinballing around to cast long strider or spells like that at camp is tedious. I wish there was a way to cast stuff like goodberry more conveniently too. Having a pair of druids supply the camp with goodberries takes like 20 clicks with as many spell animations, and then another half dozen clicks to shift inventory/char select. Like I'd rather watch a mini cutscene at that point, which would probably accomplish the same in terms of flavor.
Also like couldn't everyone just have the meta-magic distant spell when we're at camp? In act III this gets particularly tough since there are only a couple camps, and they're spread out. Running around camp is charming, but sometimes I just want to tell everyone to come gather around the fire so we can get shit done, and then they can all strut back to their tents maybe?
I wish I could just camp here some nights, in that tiny little room at the flophouse. You know like where everyone is standing right next to each other elbow to elbow. I'd take that hehe. Two bits, no prob!
Also having spacebar as the skip turn key feels pretty insane. It's way too simple to accidentally depress that key and screw yourself over without a double confirmation. Spacebar was the pause button in BG1/2. If anything it should be the button to enter/exit TB mode, since it's relatively easy to slam the spacebar when you're in a panic. Instead here it's shift + click Spacebar to enter Turn based mode, and regular click Spacebar to End the selected characters turn and also skip convo and also loot-all. So pretty much roulette for clumsy thumbs there between the various modes and functions for that key lol. I don't know, just feels like they could come with something a bit smoother for all this. I find the chains hella clunky and way too easy to trip over, ungroup summons is also hard to remember, since that has another manual click to activate the links in the chain. Seems like it's always either one person getting left behind, or everyone else doing something I don't want them to do. You know like jump down a ledge, taking damage, jumping back up the ledge only to have to take damage again, while selecting another character. The up down ladder thing, still largely similar. Companion pathing is generally much better with traps and somewhat better with surfaces, but then the companion AI and for the most part the enemy AI, does poorly with stuff like cloud of daggers or walls of fire.
Here's a screen showing the display for the concentration spell icon relative the other stuff. Pretty tiny. I feel it should be much larger and like right next to the End Turn/TB/Flee buttons or most of the other toggles so it can be quickly cursor'd over to from there...
