(I believe it is an issue with solasta)
Eh, it's not, for most people. It makes the combat more enjoyable in Solasta, which is why you'll hear the overwhelming majority of people who ACTUALLY played both games advocate for the same system coming in BG3.
And Solasta's implementation of the idea has room for improvement, too. So it's not like what they did is the most you could get from a prompted reaction system.
it is also pontentially an issue in MP.
Not really? A turn-based tactical in multiplayer doesn't play particularly different. And it's an initiative-based queue system, meaning you'll still get one reaction at the time anyway.
Even imagining the fairly UNLIKELY scenario where two characters could be prompted to react to something during the same enemy action, where's the difficulty exactly? Each one of the player involved would get its own prompt. It's a self solving issue (and yeah, one could eventually be wasted if there's poor communication/collaboration between the two players, but that would be only their fault).
That aside, I have to admit that while there are issues to address with a decent reaction system, the current absence of Ready Action and Dodge is WAY more puzzling and hard to justify.
You can't even argue that "i't's not really needed for how BG3 works" when I felt its absence in several circumstances already.
