Guild Wars 2

Hello ANet.
Loving your work!
I play WvWvW 99% of the time and absolutely flippin’ love it!
There is the occasional annoyance, however, one of which I’d like to point out to you.

Siege Golems are expensive.
Which is why it’s insanely irritating when someone unknown to you hops into the shiny golem you’ve safely parked somewhere until you need it and drives it into oblivion!
Is there any way a locking system could be implemented?
Or perhaps limiting it’s piloting to those people in your guild, or maybe even just your party?

Just a thought.

Thanks for your continued awesomeness.
