Guild Wars 2

give each weapons more skills so that their usage cycling could perform more specific functions rather than a single or general function. something like warrior weapons from gw1.

Skills to modify weapon switching cool down.

Utility set switching, much like weapon switching with cool downs to limit their usage frequency.

A skill that multiplies itself to fill copies of itself on your weapons skill bar, but each copy is slightly different in anyway. A similar skill can be done to apply the same effect to the enemys’ weapons’ skill bar that gives weaker skills but also damages and or conditions enemies when they use the skills. This could be the fifth skill of your weapon skill. The enemy may get this fifth skill too to change your weapon skills but when used on you or your allies, your skills are strengthened and you gain buffs when you use your skills. When an enemy uses the fifth weapon skill their skills return to their normal respective skills.
