If you’re unlucky with corruption you’re screwed compared to someone who lucks into a trait. I’ve got a pair of bracers with corruption on my Monk, but nothing on my Hpal or Feral. All 3 have a rank 7 cloak, do M+, raid, etc.
I’m so happy we got rid of titanforging for this next level garbage which is somehow worse.
It wouldn’t surprise me if mythic is tuned around 1 or 2 op corruptions being in the game and makes them basically a requirement. I’d be willing to venture blizzard doesn’t like seeing world first raids being done with massive class stacking, it just doesn’t look great from the casual observer’s perspective, and would rather method be clearing with a somewhat balanced raid (ie, the raider’s characters that were lucky enough to get r3 echoing void or whatever in one of their split runs)
