This game could definitely use more useful and unique skills to make more viable build options. Right now there aren't many.
I propose class and weapon combination skills. Each weapon should have multiple skill lines aside from the existing ones. The new skill trees would represent the class you wish play.
For instance each weapon should have a unique skill that benefits a tank, healer, or dps. Once that skill is selected several other skills for that combination should be unlocked. For instance if you want to use a melee weapon as a healer, there should be some attacks that heal and buff you and allies as you strike. Or for a tank, skills that raise aggro and defense.
You should be able to select a different class type for each weapon. For instance I might want to play a healer with two handed melee weapons but cc (tank?) with a bow. This would definitely increase customization and give each weapon skill tree much needed depth.
I originally thought weapon skills should reflect your chosen class but that would be more restrictive and the goal here is to allow more flexibility with weapon and class combinations.
