Hearts and Mind remains buggy as fuck. I've done it on five characters, and haven't seen it not Glitch The Fuck Out in some way or another. Usually in the NPCs getting hung up on terrain or rifts not working. Just now the asshole mentor became active again after the rift wouldn't pop, but kept the complete damage immunity. I don't think I've ever completed this mission and not been pissed off after.
I'd rather fight Zhatian. It might be dull, but at least it works.
Anecdote: When I first did the last story mission the very night HoT was launching, I did it solo. So I meandered through reading everything, figuring things out, not dying but still taking an hour before the final scene.
And then the game crashed and I had to restart and do the entire mission over again.
This is actually a cool looking Asura.Finally decided to join the llegion of revenants
