Recently Funcom posted many of their thoughts on exploits and over-equipping. I can talk about the over-equipping part. The question should be asked: why do people over-equip? They do it because it is a necessity. The problem doesn't lie in bugs allowing people to carry QL 100 guns at lvl 75, the problem lies in the fact that if a player does not have such a high level gun- he'll die. His damage will be so poor compared to, not only other players, but to the monsters as well. If someone does not over-equip themselves, they can forget about going solo or doing missions. Their only refuge would be to get in a team with a tank that does over-equip and then hide behind him. Monsters have so many hit points that one needs over-equipped gear to fight off even greens or yellows.
