Yeah, Wrathgate was one of the big reasons why I included Dragonblight on my list of "suck it up and do it" zones. In fact, I just ran through the Battle for the Undercity last night on my team.

Borean Tundra, Grizzly Hills and Zul'Drak on the other hand don't have anything like it so can be safely skipped in the main.

Storm Peaks is on the "must do" list, at least for the first half to open up Sons of Hodir, and Icecrown has to be done because of all the phasing opening up certain factions and the like.
