Guild Wars 2

With the move to more structured large scale content, would it be possible to offer a way to let players share resources to any player in an area?
With the new and awesome Tequatl fight, I landed in an overflow with 80+ potions of powerful undead slaying in my bag. (What? It was a cheap way to level Artificer)
I had completely forgotten there is no trade command(like other MMOs). So I started mailing them to the near by players, only to be stopped by the spam filter.
I’m not looking for a bonfire type thing that would tank the economy for consumables but maybe a local communal chest.
Heck for safety make it only apply to non-soul bound consumables, ration limits by the player setting the chest, and heck make any unused ration taken from the chest disappear/disable after a time limit to prevent horders looting events for profit.

The fight started, lots of players without the potion buff and a ton of the silly things stuck in my backpack being useless.

I would really encourage something like this.
Maybe A guildbanner that can be soaked in with potions.
So if you click any with potions in your inventory you get the regular message with ‘please accept this complementary service from our guild’ with an close botton. but also an extra button. If clicking it opens a window (like a bag) and you can drag one or more potions to that window. After that you get an ok message, and it asks if you want to soak the banner with x amounts of potion y, you can click yes (or cancel) and your done.

If you soaked the banner in 20 potions, the next 20 people who interact with the banner gets the buff, it also will turn the banner in a specifick colour to show it is soaked.
