Hmmm...nah, not a good idea IMO. I agree with the dude at first page who said making even higher tier weapons would make NQ ones even more worthless.

For me even the +2 and +3 are already bad enough...i'd rather you having NQ and HQ versions only and not multiples HQ tiers.

Anyway, i believe that, since the market do is saturated of some items, SE should, instead of making uber ninja ways of making e-peen, just add an option where you can exchange items at the guild for guild marks. this would be a simple way to lessen the amount of certain items at market, protecting their value.
