I REALLY hope they won't release U11 in the current state. Fortification doesn't work, hirelings are wacked unless you dismiss and re-summon them, items doesn't seem to work as advertised and quests seems buggy - some won't let you in after several tries breaking your hard/elite bonus as the quest kicks you out.
It seems for every fix something else breaks. I get that this is BIG. New class with new functionality and some of it is neat. But I can't for the life of me go beyond level 11 since without functioning fortification the artificier is dog meat. It won't take a lot of hits for someone as frail as a caster to get squashed.
