Good day, I am killing (T) mobs and receiving in the 360xp, chain 1 500xp. Back to 460xp. for tough, I am also under the effect of 50% Emperor Ring. This inadequate experience points all started yesterday after I tried level sync, which was about the time XP bonus campaign ended. I dont know if either have anything to do with me getting terrible XP. This is only on Keuchie character a new account.
To test I created a party with my other account Chupacabraa , both toons were level 5. Chupa got like 1000xp and Keuchie got 300. <- this was with Echad Ring, 150% bonus lol Keuchie is broke.

The problem seemed to start when I level synced, I was level 45ish and synced with a 99 in Eastern Altepa. I did this yesterday. Today I still hace the XP issue. Ive rebooted, logged out, re cast the xp ring. re synced and unsynced. Ive tried most everything.
Now all my xp seems reduced by 2/3rds.

ROV KI give EXP boosts. New characters will lack these enhancements.

Probably the most important thing is, that I received 300xp, actually one time, I received 260xp with a 150% xp boost from my Echad ring. Granted that was only an Even Match but still.

I waited a few days and tried again, things seem normal. >.<


Thank you
