We've made combat skippable with cheat mode activated (selectable outcomes), and currently both AI are available, but the new AI will eventually replace the old one (which is mostly just the enemies selecting their skills at random).
What do you mean "whatever i say"? Your the one that said i don't need achievements if i don't care about combat and strong character. I don't see the correlation between the two.
You could ask what do I mean, I would answer that achievements in this game give you bonuses that make your next character stronger. Rogue lite elements.
