the trouble is they don't want to loose potential subscriber, then instead to say, this is an exploit or a bug, they say nothing and fix it later. but it lead to a problem more bad the community is becoming more and more ugly as the time pass. speedrunner, trashtalking against first timer, harrassing because you break them fate by doing the fate as intended, leecher, leaver,...

indeed we do point the trouble of the gain of exp here... but it's a perfect example of how the community is because of the lack of action. the game is good, but it's an mmorpg, if the community is horrible.... well you get the point.
