The party controls - I hate the chain system. The number of times it has screwed me over, just because I clicked on a different character and they all started running around like crazy. I have nothing positive to say about it at all. Please let me select my party members like in the predecessors.
I just need to emphasize this bit even more, after a lot of curses towards BOOAAAL, our new lord of murder.
Just finished the Spider Queen encounter, and most of my party were at ~3 hp (except Astarion, who was pew pew'ing from above).
They are all standing in safe spots, and it's all good - until I click a different characters portrait, and BOOM, they all run around like headless chickens in the poison from the dead spiders, merrily killing themselves.
Not only did this trigger Gale's death scene, but that also made sure I had no time to save any of them as the saving throws vs. death happily rolled in the background.
I ended up using 3 resurrection scrolls afterwards - not because I died in the fight, but because the chain system is horrible.
