Deadfire was not meant for turn-based combat from starters.
Turns in games like forged in blood, Xcom, Battle chasers, Fire emblem (games where you fight mobs of 8-10 enemies) does never take more than some seconds and you have the option to allow "enemy faster turns" or "enemy instant turns", something you do not find in POE2 TB game or PF:K TB mod, so I understand that could give many people some distorted notions about what´s the standard in most games.
And in BG3 I doubt you will have to face so many enemies in a single encounter.

That´s why I prefer challenging fights with tactical tricks or difficult terrain against lots of enemies or few tough enemies if you do not have "enemy respawning" or repetitive fights.
