energy shield regen keystone

I was thinking that an interesting keystone would be something like what appears on the vaal discipline gem... just modified slightly...

"Damage dealt to you by your own skills doesn't affect your energy shield regen"

Would make a BM character with energy shield more feasible without making it OP... you could also put it in the witch area so that it's hard to get both unless you are a scion or burn a lot of nodes covering the distance.

Just something i think would be a good addition.

They could also just fix the mechanics of a BM character, so that blood magic skills don't delay ES.

This is an interesting mechanic that I wasn't aware of.
