I've been thinking of ways of ways to disrupt the typical ball zerg or gate defense strategies. As a solo player there's only so much you can do with a PuG. I stole this idea from a reddit thread a while back and have been working on a sort of vortex/aoe build that would serve to break up the front line or drop massive aoe inside a keep. It's a bit niche, and by no means a meta build but I wanted your thoughts:

I know I need to work out the lack of sustain, maybe by changing mundus, otherwise I'll have to rely too much on heavy attacks. Also not exactly great 1v1. Otherwise this could have some respectable damage output and Swarm Mother would really change things up. Thoughts?
