Man at this point, I would just LOVE seeing a FLAT battlefield somewhere.
I would love to see choke points. Cover. Confined spaces. More dynamic battlefields rather than always the same king of the hill race where enemies are widely scattered and given extra ranged options and surface bombs.
I want to place my heavily armored Fighter in a choke point, cut off a horde of zombies and AoO the bejeezus out of anyone who tries to get past me to reach the squishy party members. When was that ever possible in BG3 EA? Even the goblins don't have a melee horde to wall off. Or to put to Sleep.
I agree. They've given nearly every creature either an AOE attack, or some multi-hit jump attack that completely nullifies the concept of character positioning. Couple that with free disengage/jump, no readied actions, and a really poorly conceptualized implementation of reactions, and you've got some really blasé combat that devolves into the same surface/high ground/push schtick.
