Well, tbh you cant do much running 5 hunters @ lvl 85. Go for 4 hunters and bring a healer friend! With 4 hunters + a healer you can do heroics, random BGs (10-15 man BGs alot easier). With 5 you get pwnded if you let melee come close to your group, and forget about heroics at this stage. But all in all, its great fun havent had this much fun since I played 4 x ele shamans back in WOTLK with full wrathfull gear!
