XP Bonus after completing zones

[tucandroll]

the bonus works even after getting the levels you need. When the patch came out I was grinding 7-6 but not beaten all zones. after I beat the zones my exp went up 30%. I I was getting about 18k exp 2 party members. when I got back from work I was lvl 76 still getting the 18k with same people in party.
so all with only my own experience to use, I say it works.
