Guild Wars 2

Trying to get some opinions, I’m looking for a change. This is the build I roam with. Focuses on boon duration etc, I do really well with it.

Currently I always use LB, just bc I love it with AS. And have been trying various sets

My options for a secondary wep set are

1)GS
2) Sword/axe
3) Sword/Warhorn
4) Staff

Pros and cons? Which would be compliment it?
