Guild Wars 2

Empowered (Warrior major adept trait)
In-game description: “Increases damage for every boon on you”
wiki: +2% damage per unique boon

Power of the Virtuous (Guardian minor grandmaster trait)
In-game description: “Deal extra damage for each boon you have.”

Bountiful Power Power (Elementalist minor grandmaster trait)
In-game description: “Deal 2% more damage for each boon on you.”
wiki: +1% damage per unique boon

3 Traits on 3 classes with the same effect (maybe?).

Why is an adapt trait more powerful as a grandmaster trait?

Why is an elementalist grandmaster trait more powerful than a guardian grandmaster trait?

Why can’t we have the same level of information for all traits? Even better all information (e.g. how is boon stacking handled?)

Shouldn’t traits be more unique for different classes?

Different classes, different balance. That’s like saying why does the guardian get better armor than the ele? Because the class was built around that armor, not the light armor.

I thought that Guardians were build around the idea that boons make them strong. So why do boons make a warrior stronger?
