Wow. A lot of responses here. Thanks a ton for all of those who provided some input, very much appreciated. Also sorry for the delayed response. Work and all that jazz.

I know there are a ton of resources out there on how to tank the fight and what not but I find myself choking on some fights. I know Titan HM is more of a stationary fight, but what about Garuda HM? I've tried tanking that once and failed miserably. Once the mechanic came up to rotate Garuda around the map I felt like I was always inches away from the Whirlwinds. It seemed as if none of them were moving, but instead entirely stationary. I finally got around to tanking Titan HM and did fine, but Garuda HM still seems to be beyond me. Any advice here?
