Please consider adding traits or skills that would become available exclusively to particular orders. The tree different Orders seem to have their own particular characteristics and different methods of doing things. Aside from the cosmetic armor sets, a few extra benefits to joining an Order would be great.
Disabling them in SPvP and WvW would keep things balanced.
Just a thought that having some kind of stealth skill for being in the Order of Whispers would be interesting. Maybe boon to power or something for Vigil members.
Thanks for the consideration
