Get your rep.

[Blaine]

Here is a list to get you rep fast with the given faction. Im only going to list the major factions for the higher lvls. I will list quest locations, but i wont name who gives quest nor name of quest.

Argent Dawn - Kill mobs for tokens, quest in Desolace near the tower by the ocean, WPL and EPL quests.

Cenarion [various] - Silithus, cenarion refuge, cenarion near road to zang from HP, feralas.

Lower city - kill the arakoa in terrokar and turn in feathers to arakoa in lower city[takes about 300-360 feathers to get exaulted, so 150-300 kills, sometimes they drop more than 1 feather]

Scryers - kill the mobs on the south terrace of BT, 1 in about 4 kills drops an arcane tomb, almost all of them drop the signets.

Aldor - Kill the mobs in blades edge and netherstorm that are part of the invasion forces, i.e. invasion points.

Ashtongue deathsworn - do quests for BT attunement, although you dont need to, you will get rep and you can get stuff from the quartermaster.

Consortium - collect crystals from area around giant crystal in nagrand, if youre going to do instances in outlands then pickup quests from lower city consortium for Badges of Justice as well. Irvory tusks from the ellekks in nagrand as well.

Faction Cities, if you just want the rep, or if you just need to lvl, do the cloth quests at the appropriate lvl in each city.

That is all for now, I will add to this list when I get a chance.
