I actually have little problems with the controls DURING COMBAT, when you are controlling each character individually anyway. I think they could make it a bit more "snappy" and reactive, but I'd dismiss that as a technical issue that they will surely address if they can.
It's the group control during exploration/real-time phases of the the gameplay that I genuinely can't fucking stand. It's cumbersome, convoluted, slow, unintuitive.
And that's on a good day when it doesn't become openly HARMFUL to your party.
The chain/unchain system needs to be thrown in a volcano. And I'm not an advocate for violence but if the person at Larian currently advocating for it follows I may hesitate a bit to shred a tear.
