Ignore pretty much all of this. 100% added drama queen and 50% fact.
a mage would be easiest to level, there always seems to be a shortage of them, theres never a shortage of rogues it seems.
as a mage youll also only need one set of gear, and youll still have fast que times in experts once you hit 50since you can do 3 roles. as a rogue if you dont have seperate tank gear youll be waiting a while. theres also always a demand for healers and archons but hardly a demand for tanks in pugs. most pug groups dont trust random tanks and will have a guildy in good gear try to solo tank as much as possible.
