Nope, just doing all the faction ones I need to get exhalted for http://www.wowhead.com/?item=44503#comments

"This Schematic as of now looks like it requires exalted with alliance vangaurd for an engineer to learn it.

alliance vanguard has 4 different factions related to it.
- explorers league
- the frostborn
- the silver covenant
- valiance expedition

so to get exalted is it exalted with all 4 factions? or do each of them contribute their individual rep + alliance vanguard?

according to wowhead. the only 2 out of the 4 branches of this faction have quests to do. valiance has 198, and explorers league has 22.. all quests totaled give 41535 rep or 37655 for valiance and 3880 rep for explorers league..
if my math is right it takes 42000 rep to get from neutral to exalted...

i hope they add more quests or dailies at lvl 80 so getting exalted isnt so tough
