Guild Wars 2

Dear WvW developement team,

I know you want to have some surprises left for us for future updates, but can you please make some (vague) announcement about the future of WvW abilities?
I think it is fair to assume that after the Trebuchet Mastery the Golem Mastery will eventually be reality (as all all “blueprints” are covered after that). But what about abilities that allow more defensive tactics and “utility” (like Repair Mastery, or Supply Mastery)?
Trap Mastery comes to mind, but there are currently just two traps out there. Will the trap variety be increased?
Dolyak Mastery has been mentioned a lot on the forums already with ideas concerning buffing speed boons, adding protection & regeneration or denying killers the supply gain.
Tower Defense Mastery could make the life of defenders easier, if it grants a small buff on the range of weapons, or better defense stats while fighting on walls etc.
What about Mercenary Mastery that buffs “Quaggans” allied with you (although there was a hint to remove them from Borderlands), Sentry Mastery, etc.

Are there any ideas in the pipeline of the developing team concerning ability lines that go into the directions described above?
Or will new abilities just stop after the “blueprint” masteries have run out?

and each time you add a new wvw skill grant everyone a free points reset.

Saving all the points for the Omegas barrage!
