Should overequipping of weapons be allowed? of course, the buffs were put into the game to do just that. But if they were meant to permanently raise a skill then they wouldnt have a timelimit on them!. You should be able to overequip to your hearts content, as long as you have skills buffed up high enough to use it.
I mean come one here, if it takes a certain amount of skill to use a weapon and then your skill level drops, you should at the very least start doing minimmum damage since you dont have the skill to weild the weapon anymore! Or better yet, let the actual QL of the weapon reflect the Actual skill level of the player at any given time.
Wanna do normal damage levels again? then get the buff back! Either that or just dequip the weapon/armor forcing them to use lower QL in the mean time. Worried about full inventory and banks? Make another menu or something reserved for the cases when someone might get de-quipped. Although that last idea I probably like the least.
Is overequipping a bug/exploit? No, its a viable game mechanism. Is the ability to use the overequipped weapon after the skill buff runs out a bug(not exploit)? yes! It is not an exploit because funcom allows you to keep the weapon in hand and use it at the same level, but it is definetly a bug.
I dont like the idea of raising nanos to the same state that everything else is in right now. Kepp them the way they are and make skill checks, but just make everything else do the same thing.
