Guild Wars 2

The siege weapons which are currently controlled by some1 shouldnt have the option “use” for the other people.

Well, this is both unnecessary and misleading. And it will be easy to find unmanned sieges if there is many siege in one place

From the GW2 Wiki:
“The player who placed the siege weapon is considered its owner. While any ally can use the siege weapon, the owner can take control of the weapon at any time. "

There are situations when people do need to invoke “Owners rights”.

If owner:display
If not: display only if unmanned

should not be so hard to code

would help building rams that are on top of each other too, I want this feature
