Do the nerazim even have females besides whatshername? I've seen female Khalai and Khalai who lose their psionic parts that connected them to the Khala and basically became nerazim because of no link with everyone. Maybe it should be a Khalai like that.
Are you guys still using Gesalt Zero? I think that would be a terran hero more than a protoss sniper. Terrans did create him and he was originally terran he just got protoss added into him.
EDIT: Just read the other posts so ignore what I said. Anyways for the nuke if it warps in a purifier maybe we should be able to control the purifier as well or will it be like in campaign where it can't move while firing? It'd be pretty awesome to be able to move it, I remember this one game where you had control of the ion cannon and it would just wreak havoc all over the base but focused on one building or two it would just destroy those and the time limit was usually up.
I think of the the spells for the normal unit sniper should be a lockdown sort of thing, kind of like zeratul's spell in campaign. Maybe make a real hallucination too.
