if you don't have the HW expansion at level 50 your best bet for gear is Ironworks gear Ilv120 (purchased in Mor dhona) and the gear drops from the Crystal towers. If you do have HW, the gear you can buy in falcons next once you reach ishgard is gonna be the first thing you want to mix and match with your ironworks gear, then its on to mixed n match parts of the ishgardian banner sets that drop in Dusk Vigil, then on to sohm al, aery, vault, and end game. So until lvl 60 its pretty linerar. tanks ur gonna focus vitality, goon is str and crit/skill speed, ninja ( I dunno), bard (dex, acc and crit) so on n so forth.
