I actually dislike competitive play entirely because it disregards so much flavor that Pokemon should have. I actually become upset when a Pokemon knows a move it "shouldn't" (like Kyogre knowing Thunder or Starmie knowing Thunderbolt or a wild Buneary knowing Ice Beam). I can't like it and I can't indulge in it. So that question about Noivern was purely in-game value.
That's why when I RP Pokemon, I limit them to specific moves and if I run them, I make everyone do it (mwahaha!). I simply don't care for the "competitive" movesets and care more for the flavor and style of the Pokemon itself. I don't know why I'm so anal about it, but I am. >.>

AT: and you shouldn't be ashamed. It's good to be able to know a lot about something you're interested in! It's just that I have no idea what "underused" and the rest of those things mean. I don't even know what "parahax" means since Spore makes a Pokemon sleep, not paralyzed. I've watched quite a few competitive battles on youtube but never really understood some of the lingo.
But then again, this discussion isn't for competitive play (which you talked about with most of your favorites). It's more about flavor and personal connections. Granted, you being competitive will have a lot to do with what you like and dislike, which is fine. Just something I noticed, not hatin'. ;)
