if it came to a vote i'd vote red boxes. sometimes in the flurry of monsters being killed it's EASY to miss a common green box tho i try very hard to check everything when questing solo. I even the %'s on "common" weps (just for fun). you can call me lazy all you want roro. in fact, i'd agree with you. lol xD

Speaking of which, I wonder how possible or impossible it would be to add new colored boxes. Like purple or something.

Isn't that a matter of inserting new skins?

Models, to be specific.
