Only real draw back is that yeh gotta be on top of 5 different classes when it comes to patches.
yeh gotta make 4-5 different dps macro's. Buffing is kinda a pain if yeh do it manually theres been tons of time I've forgot something

I'm running

pali/prot
warlock/aff
shaman/enhance
druid/balance
druid/resto


gearing will be slightly easier.
