actually i tested arena a little now, and i like the changes, yeah it's ugly to give up on a beloved toy, but the gap between chars gets less extreme, so i think this is really okay.
cool that you fixed dusk so fast, ty for that, would wish more of these instafixes...
missions are cool too, i like the event and the thorn fixes and the satilite 15...so all in all this is an okay update.
can follow up with the prisoner bug he doesn't block block (lol):
aside this AOF gets his passive back when revived, i think this is an older bug, but still annoying. if an enemy gets killed after aof was revived whole party will get an extra turn...
