if you 5 box wsg ab av it is always best play def with shammy. you have your totems set and you can deal with most issues.

I run 3 mages priest paladin (PVE herics grp) I play off with them paldin gets them their fast in AV can cap towers and gy before alliance does if they have little or no def

I also run 5 hunters. they can do it all. very fun
