About Locust Brood, I realise it's very good thanks to one of Pally's videos, but I will not add it. I might instead buff Locust Nest to spawn 2 Locusts at once. Of course, I will double the CD then.
About Hivemind, my original idea for the "new" one was to make player cast them with freedom and much more power than "old" Hivemind, bevause my version gives these abilities as they were yours. So they ALL are talented.
But if it's weak in your opinion, I might swap it with Volatile Mutation, with buffing the overall AoE damage and also CDR for your Heroic abilities, around 25% or so. Th eventual option will be applying Nexus Blades to Symbiote host/
Also, is there something for you that caught your interest?
