so i was working on my 70pally+2 lvl 40 shadowpriests (alliance) and kinda got bored of it...mainly becuase alliance annoys me

so i am going to sort of re-roll horde, i already have a 70 BE mage on the same server, so i was gonna 3box my mage and 2 shamans, and boost them

so once there 70 and ready for arena, i was wondering

would a pom pyro mage and two ele shamans with nature swiftness be good enough burst damage to make this work for 3v3?

and would these burst specs be decent for pve?
