LOL! That’s what I’m doing now. I’m actually farming the first 10 devotion points in Crucible. Makes things easier when I hit the campaign until the Warden 
It does spawn more heroes but it could be me being biased as I seem to see more green/blue drops compared to normal. Didn’t do any testing to prove this though.
I’ll try Forcewave again following your devotion sequence as I’m going for RektbyProtoss’ Leviathan Death Knight build which also uses Cadence as primary skill.
As for my current Necromancer, are these devotions ok, especially the skills binded to the devotion procs?
Also, how is Tip the Scales compared to Wendigo’s Mark?
