spawns and avoided the lava waves

I experienced the issue May 3rd after the patch was applied on my 82 Rogue.

During the fight Hammul and acheter wow gold Malfurion were casting the debuff on Rag, but nothing more. Cenarius just stood there during the fight not doing anything besides giving himself the healing buff. Buy the time I could DPS him to around 50% he had killed Cenarius and recieved a beserker buff and then killed me, Malfurion and Hammul.

Note: I did kill the spawns and avoided the lava waves.
