Just hit 90 last night, im specced enhancement and i pretty much have no clue what to do first as far as what faction i should work on first, or even where to go to do it. I pretty much hit 90 went to the Vale and logged.
I looked on sites for what faction seems to offer the best rewards for us so I could grind them out first.
Im also herb/alch and cant find any factions offering new flasks/pots/elixir recipes. Is alch pretty much done once you hit 600?
