How is that any different than battling a team of well-bred, well ev'd Pokemon?
If you don't find battling competitively fun, then why are you posting here?
I'd understand if you were pissed because some ass brought his No Guard Deoxys-S with Sheer Cold out on you, but if you're battling with your best breeding products, you should be at least within the 1% range of having no disadvantage to your opponent scrub with 31/31/31/31/31/31 dudes if not a 0% range.
I don't want to make assumptions about you, but most people find challenges to be fun and while people ARing things don't work as hard as you do (whatever that means), they are presenting you with the best game-possible challenge which, if challenge=fun, should be the most fun for you.
If they're 255-alling, that's another thing. When it comes to WiFi battle, you choose who your opponent is. If people from a specific forum battle in a way you don't like or consistently have obvious hacks on against you PROTIP: don't battle there.
Seriously, there's no point in discouraging a guy who is looking for fun from trying to find it, as a lot of us don't seem to have the same problems you do. Unless you're a part of some secret overwhelming silent majority.
