"Creatures protected by Planar Defense can no longer be struck by multi attacks, flurry, spell double attack, ability double attack or pets until Planar Defense has been removed." C'mon, are you serious? What the point behind that? Combat have already enough things to make them slower without reason. In Solo, any named bring up a 10 second immunity every 1-3 second he receive damage, i'm like cast 2 spell, wait 10 sec, cast 2 spell, wait 10 sec, cast 2 spell. Way to play 20% of the time and 80% staring at my screen while the named decide to allow me to play again. And now this, i will have to spend 5-10 second at the beginning of every fight to cast spell just to break his stoneskin? Why? Will it make the fight harder? No, it will just make it more of a pain by slowing every instance we do. Anyway, they already have their damage received cap that make it so no spell or ascension can remove them more than x% of life, so there is no way to kill them fast with ascension or even high damaging spell. Why make solo fight drag for even longer? Same logic could apply for heroic.
