Combat currently is an unplayable mess. It is mainly luck if you win, since everything has some kind of weird random chance attached to it. Ah... and the only "tactics" is to win the climbing race to "high ground". If this would be a parody on Star Wars Episode III, it would be fun, but unfortunately it is not.
That you own people are too dumb to step aside when a party member wants to pass them just adds to the disaster.
Honestly, they should add a difficulty level 0 where you have a button "win combat" that just kills all the enemies. Would be more fun most of the time.
I have no idea how they could think that this is fun.
