I'll leave the calcs up to people presenting arguements, and I'd prefer if they were based around these sets.
My opinion:
Personally I think Heracross is a huge offensive pressure and right now there is not much there to stop it. It 2hkos a majority of the meta, reversal/megahorn ohkos the other half. Weezing seems to be the strongest counter which can easily feed Hera a Guts boost. Bulky Hera is also capable of surviving multiple flamethrowers, and pursuit trapping ghost types such as Gengar and Dusclops which otherwise stop it. The most overpowering aspect of Hera in my eyes is megahorn and its spamming ability. Yea the shit is resisted by some pokes, but othewise it ohkos/2hkos the meta (calcs plz). I'm not in the mood to type anymore..
Hera fine in OU, or to the dungeon?
[Clarification: I don't have a defined stance on putting it in OU or Ubers, but if there is an argument strong enough to make a change, I'd rather the change happen sooner than later.]
