On a fresh 90 best bet would be timeless isle, if you cant get exactly what you are after a little visit to the JP gear vendor will bring you in line for lfr current content. Shadow-pan Assault would be the only faction worth doing, and thats through LFR or raids anyway. Dont spend VP on upgrades to timeless gear though, spend it on drops through raids. Oh, maybe worth dailies for a bit to get your cloud serpent through The Order of the Cloud Serpent, if your not exalted with them you cant ride it even if you have it on another toon. Perhaps The Anglers too simply for the Water Striders, a very handy mount that can walk on water. Also cooking dailys/farming if you like the idea of farming your own stuff... It only took me about 5 days to get the cloud serpent on a second toon with the account bonus, I'm still working on the anglers, dont have the bonus.
