Guild Wars 2

Would be nice if this box is a guaranteed drop on every raid boss, or maybe add a repeatable achievement like dungeon frequenter that reward this box for every 3 boss kills.

I’m pretty sure if box of raider supplies dropped reliably every 3 boss kills it would crash the market for ascended mats. I could see maybe getting one every week for re-completing all the boss kill achievements or something. But even that might be too much.
