At the very least, I want to see "Ready Action: Attack if enemy closes", because right now if warriors don't have quite enough movement to reach an enemy, they're stuck. It's really unsatisfying watching enemies stroll up and hit your character because you don't have any ready action to attack.
This is the main reason to want ready actions in the game. I know that one of the bigger community concerns is how boring martials feel to play at low levels. People think this is an issue of lacking things to do, but I think the real problem in the context of BG3 is that they have few things that they can do if everything is out of range.
And the lack of ready actions AND reactions means that by default, the overall tactical balance swings wildly towards offensive strategies rather than defensive. There's really no answer to the high mobility/AoE spam tactics right now, because the major answers to those don't yet exist in-game.
