Refining Ragnaros Strategies

[Quark]

Repeating and/or Counteracting what some people said above, but here's my list (partially stolen from my own thread!)

First off, make sure your groups are set optimally. Shadowpriest (Vampiric Embrace) and Paladins go to the meleers first, excluding the MT healers. Melee DPS isn't best as 4 rogues + pally. Rogues do much better damage with a warrior in their group to Battle Shout.

Rogues have to be very careful about the knockback. Getting that right is most of a Rogue's DPS in this fight. The knockback is something like every 30 seconds. If your Rogues are getting hit by it, they're not in the right spot.

Now, there's two problems with this. First, the initial knockback will not show up in CTRA or similar addons. The rogues should be timing it themselves. Second, when Ragnaros comes back up, you'll have no idea how long till he does the Knockback. Rogues shouldn't jump in until it happens. At that point, CTRA will once again fail to time the next one right.

The other part of the knockback is that it wipes aggro. So my sequence is something like this:
Backstab, Backstab, Backstab (Knockback warning).
Backup to edge of lava.
AoE Knockback
-- IF -- tank resists Knockback, jump in right away
Feint, Slice and Dice
Backstab, Backstab, etc

-- IF -- tank is knocked back, you must first wait for MT2 to get aggro, then do the same thing.
