I've been thinking the WoW forums will think your ideas are pretty fucking great.
About guardian spirit.
Ive been thinking.
We need something nice looking in our tree. How about a guardian spirit that stays at your side, maybe hovering at your right shoulder, giving a smal, balanced passive effect, but mostly looking really cool.
And ofc the on scarifies effect needs to be upped a tad. 20% would not be overpowered. thats atleast one hit taken after death.
