I think with the upcoming design-a-weapon contest. You have to wonder where these weapons would be going to. Some says it's GW:EN, other think that these new weapons might be used in GW 2. Mind you that we still got a year or two away from GW 2's release but what can you do with these new weapons that they gotten from the contest?
I think Green Weapons won't go out of style and that A-Net will keep putting out green weapons in future GW series.

If the argument around guild wars is that it is supposed to be about skill and not grind, "easy" access to green/collector/ or any other type of max weapons is a good thing. If you want to be 1337 and have the time/gold, go buy an expensive skin to differentiate yourself. The way it is allows the casual gamer to be on the same playing field when it comes to mechanics.
