Best bet is to work your way through your +1 relic. Through that you'll pick up gears from some of the first lv 50 dungeons i.e AK , while accumulating tomes for buying your high end game gear. Once done with relic I would pace myself through a bit of the first coil, since you're a tank getting a que shouldn't be that hard, but I dunno I haven't done T1 in like forever so I don't know if it is still populated even with the flux of new players.
