Should i switch from alliance to horde?

I was thinking about doing this for a while. i have a 85 paladin, 78 druid, 70 priest and every other cl in the 20-40 range. i was considering faction changing the pally and druid, then just starting over on all the others. i want to do this because im sick of the alliance sucking, and none of the races look cool and i want something different. should i faction change or completely restart?
