I agree that Loki is very annoying now. Was sitting top of the PvP by a mile yesterday then got in a tough fight while shield hopping and even though I won, the constant purple spamming and trickery AP steals from Loki meant the win was so slow I'd lost 70 points by the end of the match. Still finished 1st, but that could have cost me. I'm torn whether to kill him first to avoid such issues, or leave him to the end because there are more directly dangerous opponents to tackle (usually XForce and 4Thor).
BP's key power isn't RotP, it's BP. Sure there are 1k strike tile moves now with gamora and rocket, but those are a lot more conditional, and are 4 match moves. BP is by far the best 3-move strike tile move
I am a little surprised to see Magneto rated so high; I guess because of a great pairing with XForce. If you do not have a usable XForce (say, having it at 2/2/5...), wouldn't you rate it under Lcap?
