Some of the fights can have a lot of verticality to them, and using the terrain to your advantage is very helpful. My cleric would let it rain on an enemy group, and my sorcerer would cast a lightning spell, electrocuting the whole bunch. My rogue would sneak in before the fight and get in position to push that archer or caster to their death. Things with so much depth are easier to execute with a round based system. It's very much a game of chess, where you plan ahead and take advantage of enemy mistakes, and the two examples I just gave are on the level of a peasant like me. You can pull off some crazy shit in this game.
