Like so many of us, I have been playing a plenty in the last couple of days. And many of the quirks and feedback given already is something I also experienced. But the more people say it, the more chance that Larian picks up on it. So in that regards, I am putting my 2 cents out there.
Please, change the party mechanic by having them not grouped together as default. Plenty of times a plan has gone to sh*t because I forgot to unchain the characters and they stumbled after me, when I already had them in position.
Another thing that would help this greatly, would be to be able to select all of the party by just dragging the mouse cursor over the screen and selecting them that way. Just like any rts out there. Maybe even have keybounds to chain\unchain them together quickly.
And staying on the topic of character selection. I have also noticed that selecting the characters by clicking on their portraits does not always trigger them and you have to click them again to actually select them.
And now something unrelated to the party. Please Please, stop having back to back to back skill checks during conversations. I had to do 3 intimidation checks in one conversation to get the result I wanted. This is not fun. It is fun the first time, but after having the thrill of succeeding it and being confronted by another skill check and then another was not so fun. If my DM would be doing this in my home game, I would call him out on it and explain to me why he thinks this is necessary.
