Even trying interrupting Calibrating Shots on the 3 droids with 2 tanks, and 4 dps the dps is too spread to down the three of them quickly enough and on top of it the casting classes lose dps when they cannot finish the casts or channel abilities.
Any developer knows whats going on? Any guild has found this bug/buff to difficulty?
Personally I haven't noticed any difference from before.
Why do you split the DPS? Why not just have a tank interrupt a droid each, and send the 4 DPS on their "own" droid? Surely 4 DPS can handle interrupts between them, and the debuff synergy means that stacking DPS on 1 target is more effective.
