Missions I think are 120, mercenary tasks I got on sub 120 chars...like 118 maybe. If you have more then 6 account , u can even raid invite them - 60 kills = 6%xp + another 5 or 6% for first time mercenary in Laurion Inn. So my main groups gets like 21-26aa per kill task x 6 and the 2nd group reaps the lvl xp. The only negative to this is whatever group xp bonus you are losing by being in raid. Everyzone has simple repeatable kill tasks with very short cooldown timers.
