Which legendary would you be excited to face most?
Mewtwo for me. All of our current powered up Pokémon wouldn't stand a chance. The idea of having several Dragonites or Tyrnaitars attacking at the same time to defeat it sounds pretty awesome.

I know, but you asked which pokemon we'd love to face, and for me it's Zapdos; it can be beaten with a different variety of pokemon for sure, but still I'd love to face him; about Mewtwo, I think SE dmg with Crunch would be better than Stone Edge in every situation, above all if we'll be going to face a Mewtwo with psycho cut and remember that Tyranitar will be getting x0.8 from Mewtwo's attack (even if of course it should be immune).
not really an answer to this post, but i really didn't want to post a new topic.
i would hope that in the future, pokemons would have a grouping (ie Legendary, Rare - or something like that) and each gym would only allow a certain number of such. It'd be horrible to see a gym full of mewtwos. Another thing they could do is perhaps limit the number of mons to 1 or 2. So max 2 dragonites or blisseys. We'd "hopefully" see more variation and with lower CP mons, more turnover. I don't mind stagnation when I'm in a gym, but when your team isn't the active one, then you're stuck keeping the others at bay on your own. This is probably the simplest thing to implement without having to do any promotions or much programming. oh well...gym full of blissey's and dragonites it is. . .
