I've noticed a few differences between the official exp given by monsters on Ratemyserver (which is the most updated database I have seen thus far) and our server, and I was curious if this was an SVN difference or if certain mobs have had their exp reduced by the Game Masters. A GM's official response on this subject would be greatly appreciated.
Make sure you're not taxed, or that the monster was full hp when you attack it. Also if you have a pet and they damage the mob, that's exp you don't receive.
