Guild Wars 2

Thieves have a lot of Signets they almost have to use, why not have a trait like Signet Mastery like some other classes get?

for example:

Signet Mastery: Improves the passive effects of signets.

Assassin’s Signet: Deal 5% more damage.
Infiltrator’s Signet: Regenerate two initiative every 10 seconds.
Signet of Agility: Increases critical chance of Caster by 5%.
Signet of Malice: Increases the heal amount of Signet of Malice by 20%.
Signet of Shadows: Increases movement speed by 8%.

This would allow more customization for other builds.
