So back to the old boring discussion of over equiping.
Well are you at Funcom going to take any kind of actions to limit over equiping, which is the reason you had to boost mobs to rediculus levels to begin with.
The suggestion of having a max QL depending on your Lvl has been the best I have seen put forth so far. Just put max QL a number of Lvls above actual lvl (15-30%). With that put into place you should be able to balance the game a lot easier.
