From 55 to 65 i was mainly doing 5mans with my 70 druid specced as moonkin (instead of my imba feral gear) and 4 ellys.. worked alot faster.. Just nuke the shit out of all you see... I little trick there is to specc all your alts with Less threat.. while keeping your main without the talent.. also use earth or flame shock on alts.. and frost on main.. that way your main will take most heat and yo dont need to target healing around to much.. i use a key that make my main nuke and my alts /target main /lesser, which works fine in pve

Keep it going nuking style
