Yeah, I honestly didn't realize it was a Nghamu's type/Dervish type deal until I already linked it. It's fine though, I can easily dump a socket and put in something that benefits from the same supports as phantasms (physical, spell, proj) like certain Spectres (titty bitches, stygian revenants, devourers, Blade Vortex bois).
I have 0 problem right now but I'm completing my atlas so I'm just filling out my T5's right now at lvl 86. However, I've played summoner probably 5 leagues total and I can tell you they're definitely better than they've ever been. Damage on Zombies especially seems to be overtuned. My zombies don't die anymore. Not to anything. Unless you specced minion health and used Minion life gems and stuff, that never happened before. They'd die to the odd big boi hit or degen etc, but they're gods now. And their dmg is pretty fucking great on a 2 link.
Pretty sure Monte's grasp is going to be meta for blight clearing summoners though. Only thing I can think of with mob health scaling. When I was using them earlier they'd hit 4 mobs in the front of a full line of blighties and they'd all die. Just massive chain reaction. And now with shit like pulverize you and some of the new ascendancies, you can really juice the AE clear. My 4 big bois were 2 shotting entire sides of legions. Like, before they break out. Just walk up, hit them, they all shattered. It was unreal.
I'll stream some of it or make a highlight later. My gear is absolute shit besides my Soulwrest/Tabula right now. I have no curse/equi etc and I'm running fucking purity of elements b/c I don't have uber done yet. So I don't want to "show off" this half-assed product even though it clears like a champ(ion).
Oh and I luckily found 3(!) wasps nests I sold to fund my Unending Hunger. It's pretty good but honestly with phantasms/zombies/carrions they don't get NEARLY as juiced as they used to.
