I know I'm late to the party, but I made a toon on outlands at first I was like awesome, get to level 70 do endgame, well what I encounterd was everyone was mostly a dick, unskilled players, no one had attachments to there toons, nor did I, leveled so fast, well I made a enhance shammy on medivh and man am i having fun leveling, joined a guild thats very social i look forward to jumping on and talking to those people, in the end I wouldn't say it was burning crusades content that made it great but the community it had, which medivh does have compared to the spam fest on outlands, so in the end roll what's gonna be fun for you man :)
