True I wasn't considering MMR when I said that, the highest MMR match iv'e done was with an MMR of 56% and there 2 shots from a grunt can bring you down to wounded, 3 for a death but that was just another hurdle for me. We ended up winning those matches but struggled allot without good rewards. I cant recall ever seeing an Antag around the 56% range but i'm sure it would of been even more challenging then that.
And yes I'm also aware of Valeria's potential. I think for her they need to make that monster that comes from the Whip killable and cause an Ability Cooldown.
