When the dead shaman keeps trying to spawn things, for some reason it really bothers me and makes my stomach sick. Is there some way to disable seeing what they do?

I don't think so. When a shaman does that, I randomly think "noob sham"

It doesn't do the same for me but it gets confusing on dual shaman maps because I might think to jump on something I think the shaman that's alive might spawn, so then i'd end up dead. I think you should only be able to see the dead shaman summon things after death if they have the skill that lets you.

You either Have to deal with them or take this

"Display Evocation"
that's what i think...
