Large encounters in a TB envirorment means staring at your screen for 5 minutes waiting to take your turn. It's the main issue with Deadfire's TB mode.
When I last played Battle Brothers there were 20 enemies or something on the map. I rolled my eyes and said "Fuck no, I am not doing this shit anymore for a measly reward" and quit. I never touched the game again.
Large encounters in turn-based games are annoying as hell, which is why the term "trash mobs" exists. The only turn-based games where I never had the feeling the combat was dragging out were Fallout 1, Fallout 2 and Underrail... probably because they aren't party based.
