You can do instances with 2 with patience. @32 (First Gorilla ingame) it's a lot easier with AoE aggro and AoE dmg is quite nice. I Would get the druid a healer+3BM hunters is insane and keeps surviabilty and you can rezz + Combatrezz. Could do some mele dmg too because most of the time your pet heal is enough to heal through and the druid has HoTs so there's no prob with that.
