I think Storm mages bugged ?

I looked at dmg tooltip of my mages just before entering bossfight and it was 58k... Unsummon one mage summon him back and we have 100+k as it should be!
During the fight i noticed pretty low dps, checked tooltip again and it was 58k!
Unsummon 1 mage summon him back, got our 100+k tooltip (during a fight it was a hard task clicking +- and runnig around) - boss shreded to pieces in a few sec. Looks like they broke something :(

And btw it randomly "forgets" my options about how many mages to summon with weapon sets. Sometimes it takes a few maps, sometimes it happens every map.

And btw storm mages keep attacking ground near the target... not the actual target. Still not fixed.
