This heroic is hard as hell. My guys are wearing some 359 and 346 blue heroic gear. If you have better gear it should be easier. So far I have killed Tyrande and this is where you have to put your team. If you put your team here you can avoid the spinning ball of silence/damage. I am working on Sylvanas but I don't have the dps to kill the ghouls fast enough. The key to her is spread your group out then dps a ghoul and run through the opening. I need to work on my macros and buy some gear to help with that pain in the ass boss.
