I always ditched any Skitty that had Normalize. It basically ruins its decent movepool, but it doesn't have the stats to back it up.
And yeah, it's a version exclusive in White 2 as well. I only picked Black 2 cos I preferred Buneary over Skitty, Gothitelle over Reuniclus and I also played the original Black, not to mention I loved watery Reversal Mountain rather than the lava-y one. I also liked Black/Black 2's Opelucid City better than White/White 2 although the latter has the better music.
I have to say Janna, what Pokemon did you like using in B2/W2?
