well for one thing you don't get an sp/xp reward for completing a leve, all your sp/xp is rewarded for killing the mobs in a leave. You also get % bonuses for party members and you can link the same leve for even higher bonus. on top of that you can use guardians aspect to have an even higher bonus. Then you have 36 hour reset timers, which what was fov timer? couple of hours?
