I did a bit of a search and didn't find anything, which I found a bit surprising. What combination of skills leads to the biggest theoretical damage number you could see pop out of a mobs head? Assuming a critical hit, ideal gear for all classes involved (like Allagan weapons if you want to make a case for MRD, THM, etc...), and that any level of party buffs are available.

Is it BLM with raging strikes, astral fire 3, flare on a foe requiem target?
Can a DRG beat that with a Blood for Blood, Power Surge, Dragonfire on a foe requiem target?
Could MRD creep in the game with berserk, raging strikes, blood for blood, maim, butchers block combo'd on a storms eye'd target?

What's your pick?
