Anything that fucks over RNGers is good in my book. Real men SR/breed their Pokemon (the changes HGSS bought to breeding makes it quite painless, actually, if you know what you're doing)!
Anyways, Random Wi-Fi is fun. Mainly competent players, often Japanese, but it's getting more and more diverse as time goes on and more non-Japanese players beat the game and put together a good team and stuff. I faced a guy with 1390 wins today, actually. Pfft, those guys with less than 100 wins using weather teams. This guy was a man and swept me with a good ol' Feraligatr! (Interestingly, the Trainer Card tidbit you see before you fight him says that Feraligatr is his key Pokemon, which is shown by just how much it kicked my ass. Never knew you could build a team around Feraligatr like that!)
Note: Singles is Bring 6, Pick 3 with a banlist and stuff BTW, before anyone gets confused.
P.S. Today, I learned that Feraligatr's Japanese name is "Oodairu", which is "ookii" (big) + "kurokodairu" (crocodile). Japanese names are better my ass.
