Well you've got plenty of hit so that's not it, you're 3/3 Feral Instinct so that's obviously not the problem either. How do you normally go about initiating your AoE pulls? If you find yourself in groups where no one else is using an AP reduction talent on the mobs you can drop Ferocity and pick up 5/5 in Feral Aggression which should help with your AoE threat as well as help you take less damage. Normally I'll Enrage, FFF something, charge in and Demo Roar, position myself to where all the mobs are in front of me in a conical fashion if possible, then just start laying on the swipe. Keep Demo Roar up though or bust it out again if more adds arrive to snatch them up quickly. Growl or FFF things every now and then if needed (get yourself a mouseover growl macro and a mouseover FFF macro and a modified mouseover mod/addon [like tiptac or cowtip or something] so you can mouseover all the targets and see your % threat on them, and then growl or FFF if needed without ever having to change your current target). Doing that, I never really have any problems. Sometimes I'll pop Barkskin if my healer is off in la-la land. Gotta make sure all of them stay in the swipe range though, some may be lingering on the outskirts and not picking up the AoE.
Are people pulling off you in AoE's? If so, what classes? If it's a rogue or a hunter make sure they are MD/TotT'ing you before these types of pulls.
edit: macros - just choose the ? icon and put a space as the title for these macros and it will auto show them as the spells they are
mouseover growl macro:
mouseover FFF macro:Code:#showtooltip Growl /stopcasting /cast [@mouseover,harm][harm]Growl /startattack
^if you don't have an enemy mouseover, these macros will just cast the move on whatever you're currently targetting (since I use a lot of mouseover macros i usually just keep my mouse pointer hovering on the boss/mob's target frame that i'm currently targetting until i need to use a mouseover move on something else. that way i'm not accidentally casting my mouseover moves on some random ass mob that i don't realize i'm mousing over, when i'm really tryna cast them on my current target).Code:#showtooltip Faerie Fire (Feral)() /stopcasting /cast [@mouseover,harm][harm]Faerie Fire (Feral)() /startattack
