Well, hunters can run when stealthed giving a great advantage in arena. And lets face it, if you kill a healer on the opposing team, your chances for a win is good blizzard gave hunters a larger utility of pets in cataclysm! With 4-5 hunters you can stack great buffs which will give you awesome survivability in BGs and arena! Im currently leveling 5 hunters, main is lvl 81, rest is lvl 73. And I must say, Ive never had this much fun in BGs. Not even my 4 x lvl 85 shamans have this kind of dmg or burst right noe Im using a devilsaur for reduced healing debuff + 5 % critt, corehound for 25 % reduced casting time + bloodlust, raptor for 12 % reduced armor debuff, silithid for stamina buff and going for a shale spider once my main dings lvl 82 for the kings buff
