All of them.
They’re just the talents we would have had add to the trees anyway with any expansion, just cut off, given silly names or names of things the players have wanted for years- dashing their hopes, and called “Hero Talents” (/jazz hands) to make a so far pretty hype-less expansion sound more interesting.
2.5/3 priest hero talents being named after Starcraft units is funny to me. It’d be even funnier if in order to get any benefit out of Archon you needed another Archon priest around and the 2 of you fused into a single unit.
It’s also really telling that all the hero talents named after starcraft units are protoss. Wonder who their favorite race is.
I don’t think every class have shown all of their hero talents yet, have they?
We know all the names, if not the talents themselves.
Someone just wanted to name it after their favorite band.
Billy and Mandy…what a great show.
