Mostly I level through roulettes too, though at Lv69 I’ve been specifically queuing for Abania since it’s the only chance to run it and earn EXP (three runs = level up to 70) and I want those pretty weapon glamours, especially the arcanist’s grimoire. (I reckon they’ve deliberately put nice glamours in that dungeon for that exact reason - there’s very little chance of it coming up in someone’s roulette so they make sure people will keep queuing for it!)
