This is why I don't do anonymous PvP on pretty much any game.. people are so obsessed over being "epic" or having an "epic record", that they ruin the online experience.
Though, personally, I still do most of my pokemoning on 4th gen games, so I can trade between Diamond/Pearl/Plat/HeartGold, and so I can still migrate from GBA games. The gameplay of B/W is awesome, but so far, it far from outweighs the benefits of all the breeding/training features I get from the 3rd/4th gen games, as well as ribbons, move tutors, battle frontier/tower, and so on and so forth.
But I will admit, I love how easy it is to manipulate IVs when catching/breeding pokemon in B/W.
