Guild Wars 2

That doesnt make any sense either.

You get a 2nd weapon right after your finish the prelude. Plus all main hand weapons have it, not just the one you start with.

I know all of that.

If you only have one weapon equipped, it unlocks a 3ed ability unique to that weapon.

Whats the point? None of the one weapon only skills seems to be worth running around two abilities short.

Why would I want to run around with only a main hand weapon, and no off hand? None of the skill unlocked seem to be worth it.
