Goldvise talking, In MoP, what is the highest level area called (fx. Icecrown in WotLK, Twilight Highlands in Cata)? Are there huge 90+ elites waiting around being dropped to the ground? Would it be ideal to strike there on day one and level my 5 mages there while filling AH with all the new stuff cloths patterns etc?

Or should it be boring questing (for the rep) and then acquiring tabards and zerging instances (for more rep and exalted gears) for possible raid instance trash farming (fx. BoT, Firelands) ?
