Guild Wars 2

One handed weapons would increase thief build diversity but twisting fangs has no off hand. Because dagger alone only has three skills one would think Twisting fangs would be unique. However, it is a stand in place attack skill with hardly damage or conditions and a long cast time.

For example, adding a parry feature to it would be unique to thief.

I don’t think wielding only a single one handed weapon (and nothing else) is part of the intended design since that would mean you can only access 3 skills. I’m certain the existence of twisting fangs and the other slot #3 skills on one handed weapons are there just to ensure you have something to use until you get an offhand weapon.

I kind of want those skills to be useful and interesting, in the way that I want all skills to be useful and interesting, but I don’t think encouraging players to forgo an off-hand weapon is a good idea.

Priorities. Short in supply around here.

That skill will never be useful, it only exist for newbies to learn about dual attacks when they finally get an offhand and see it change.
