Thanks for input. In my opinion It may be a bug, maybe not and bliz did it on purpose(at least till 2.2). The mimics could have their own cds and cast abilities but copying only the spells of player's castbar. I can't know how much dps could come out of that in 2.3 or if it is viable but worth trying. You see it is nice to have your spider queens stacking all together and not die(due to no health pool) and not stay back like fetish army and sycophants do. I think it may apply better dps and have no losses like staying back and behind walls like fetishes.
Also Tagger I understand that the player may cast only 1 at a time, but if this bug ( or whatever it is) could be part of a build?
In 2.2 my spider queens did 5-10m each and in PTR i managed (with not optimized gear - just the basics to make it work) to make them hit 120-150m each.
Has anyone noticed about how many spider queens pop out of the mimics? In 2.2 I see about 15-20(correct me if I'm wrong) and in 2.3 I hardly reach 5-6.. I think it would be obviously better dps with lots of them with the new sets but if it's a nerf...
