It's hard to say no to Yoo-Hoo chocolate drinks...the name literally beckons.
Tactical Disaster - Stormrage-US
16/16 Heroic T14
10/13 Heroic T15
I personally go Holy for this fight (Dual specced Disc/Holy, with a pretty strong preference to Disc, the spec I know and love). Divine Hymn is a ludicrously strong CD now, and really, Body & Soul helps a lot during progression as well for Ice phase (As much as I wish the speed boost was not necessary, it invariably is, so, at the end of the day, the talent is useful to us). Disc is by no means a bad option for this, but the again, it all depends on how strong your healer companion is. In my own case, I'm always the stronger healer - I never get outhealed, by anybody. Whether by class or skill differences, this usually leads to me carrying the heavy healing phases - and as such Holy is a good way to go for me. I'm more needed for the up-front heavy healing (Holy) than the finer details of it (Disc). Both specs can pull great numbers on this, but they provide substantially different kinds of healing; which one is more beneficial to you is up to your healing compantion, your raid, and your own ability to play either spec.
Imo, as always.
I don't know half of you half as well as I should like, and I like more than half of you more than you deserve.
