This sounds amazing for summon druids, don’t think they could even clear the game before? Let alone one of the toughest level 85 areas in the game solo, congrats summon druid, I’m sure they are happy for the big improvements! 
Now we just need to show summon druids that there is a skill called poison creeper and rabies and if you bite the monsters once, it spreads a very power poison effect to all the monsters to make all your summons kill the monsters faster - even a 1-pt investment with +skills would be a very good addition of AoE to the build, like a necro’s corpse explosion almost?
