What would the best main DPS class to use for a 40-man raid setup?

Once you get to a certain gear level you basically get infinite rage. You just have bloodthirst & whirlwind, and can macro heroic strike into just a few of those. The browns will top meters with just quest/dungeon blues.

i just want to emphasise that he should atleast compare the dps between arms/fury/frostmage in the setting he wants to run MC, like full preraid bis with all world buffs, sure fury will be ahead. Not preraid bis/most quest or random dungeon gear, no consumeables ect...then all you need is a good 2h weapon and arms will do better especially since half the boss encounters and most trash you really shine with sweeping strikes. But you dont want to farm 20x hoj, which is like 1k angerforge (soon emp) runs or not even gearing to hitcap, Im afraid a crap geared mage outperforms a warrior at that stage. And keep in mind there is a decent amount of loot in MC for mages compared to dps warriors especially when you cut ragnaros out of the equation (which we can certainly do).
