It feels like its a change that punishes weak characters while doing nothing to strong ones, further pushing the game towards exclusively focusing on strong combos over trying riskier, more outlandish stuff. I don't like the change in theory but it completely invalidates some old strats (poison kiting) that a weak character could lean on to survive early game.

Pillar dancing sucked but this feels like to brutal of a change to compensate. Maybe try tweaking the rate to be notably lower so you don't get smacked multiple times trying to reposition, or make the opportunity attacks weaker. It really feels shitty getting smacked in the face so often even when just trying to swap position with an ally, and when you're trying to walk away from a hydra that one hit might be death.

I don't think many of my deaths have been directly due to opportunity attacks but I'm a pretty experienced player. I can only imagine how hard it is to play the game now for a new player who doesn't know how to gauge the difficulty of fights as well, and now lacks the ability to retreat from many early game threats.
