But when a poster just wants to knit pick about different types of arrows not being in 5e, or jump not being in 5e, or height advantage (which I actually like if it is just ranged classes it affects) I just don't think that really helps development overall.
I think you're fundamentally misunderstanding the critique, here. The problem with everybody having firebombs/arrows is that they quickly make every combat exactly the same. That was the problem with everything making surfaces, combat became a game of high ground + spam surface effects. It takes any depth or strategy out of combat and makes it, honestly, a boring slog after the novelty of "big explosions" wears off.
I guess for some, but I am on my 3rd play through (I just got the game like 5 or 6 days ago), and I have yet to use firebombs at all honestly, I just sell them for gold. You as the player could choose not to use them for more strategic tactics. Personally I like focusing on positioning, and use of each class in my fights. The mechanic is there for people that want them, and can be ignored by people that don't. So am I missing something?
For less strategic tactics. If you're using strategy they're extremely powerful and extremely readily available.
Wait, so your telling me it is less strategic and entertaining to actually place your range on high ground, use the terrain and play the characters strengths rather than spamming grenades stuff. Yeah you pretty much lost me there, but you do you. A trained monkey can keep spamming grenades, just saying. Also, every goblin does not throw grenades, and if a NPC gets high ground, you can use the pull ability to yank their ass down, or use the push/arrow to knock them back. Oh wait, that isn't strategic, I should just keep lobbing those grenades. I think I will still play the way I am, and you know actually enjoy the game lol.
