Hi,
this is not realy a bug, more a feature.
When you use a siege weopen, you can set it up with 1 and canel it with 2.
But if you press the button left beside the 1 on your keyboard (^ and °), you can drop the box and anybody can pick it up.
Many guys in my guild do jumping puzzels with 4 diffrent twinks and trade all the sieges to there main, while also getting the PVP marks because they are account bind.
You can only do the trading with someone that is inside a WvW battleground.
In my guild we also use this trick to supply our siege master with trebuchets.
If he sets them up, he can kick out anybody, at anytime. because of the "use your own shit" function that prevents other from stealing your sieges
Comes in realy handy if you protecting sm and the ****ing noob is shooting on battlemarks instead of killing the trebuchets that are slowly opening the wall.......
hope this is not a repost. See ya in Combat.
