what other games do you play, if you're just playing WoW (I raid ICC as well) then you don't need anything more.
Also, what realm you on? EU or US?
I play on Gilneas >> Horde >> USA
My characters are:
Thankthetank (Mix of ICC gear trying to get 6k GS)
Balockobama (Mostly Naxx Gear but starting to gear him up now)
Coldcow (Naxx Gear, havent touched him since nax came out)
Me and my RL Friends and co workers are starting a 10 man raid guild with hopes to be #1 on our server when Cata comes out since 10 and 25 mans drop the same loot just not as much will drop in 10 man.
