Yeah I experienced that as well on my shaman. Each of them has 4500+ resil and with my trinkets and all my abilities popping best I could do is instant kill the 1st target and maybe the second with in 15-20 seconds and after that the rogue/feral druid is on me and I am dead as the last healer keeps those knuckle heads up in 5-4-3-2-1 earthquake while I was trying my best to burst down the last healer or DPSer as my shaman start to drop while dancing in healing rains with healstream up. Uggh.
