There is some unidentified bug that is allowing people to level really fast by killing things far weaker than them.
As a result, I have taken the trainers out of the game. In addition, it is likely that everybody will have their XP reset to what it was sometime today or yesterday.
Sorry for the inconvenience... remember that this game is in Beta testing. When I was a beta for Asheron's Call many years ago, we got reset to level 1 dozens of times. As such, I do not like having to do resets on our players.... we will make it as effective but as painless as possible, hopefully leaving everybody with the XP they "should" have gotten had the XP system been working correctly.
