I'm killing a warbringer spawn and scouts that get in the way and they drop Shado-Pan, Golden Lotus, August Celestials and Klaxxi rep tokens. Each rep has a token for 1k per shot, ~3 drop per kill.Frostwolf Orcs, Arakkoa Outcasts, and Laughing Skull orcs (although he's only a 50 rep kill, may not be worth it).
I think that's all the launch reps except the PVP one.
edit: and success! have a triceratops mount. Now to go trap one.
