Against Loki for mid herald. Strange beat Loki's ass even when Loki stole all his artifacts.
As for Ultron, I dunno. I say wait and see how the new one does. So far, Low herald looks alright.
And.........., no on Apoc getting a bump. I like where he is. 😛 He can beat down half the people in his current tier, so I say leave him there.
