I think the amounts of skill slots is fine for the beginning of the game.
Because it is a beginning of the game.
Stunning your own characters standing in all that blood can be bothersome, but magic armor is supposed to prevent that. I dont get that situation a lot so i dont mind it. But those blood pools should be smaller and electricity shouldn't affect them so easily when we are aiming at an enemy character, at least when weapons are used.
If you mess up a conversation, you can always try it with another character and that solves most of such problems, except those that are specifically tied to the main character, maybe. I dont get any specific confusion about replies and consequences... but maybe thats just me. I like that not everything is easily obvious.
And you can always save before some significant dialogue.
So far i can make approximately as many action in one turn as i can in DOS1 so AP change doesnt bother me yet. We can still save some APs for the next turn which is the best mechanic that was needed in AP based systems since long ago.
