Shado pan or Shado pan Assault? The forme rjust do dailies (which are pretty much everywhere and hard to find), the latter just run ToT LFR over and over.
On the Warbringers, one spawns in each area aside from the vale (map). They're on a 45 min - 1 hour respawn time, and if its anything like my realm, they're going to be camped to hell and back because they're decently easy to solo now. Specially by hunters. Damn hunters... /grumble
