Guild Wars 2

Guardian Valor Trait IV Strength in Numbers gives 150 toughness to yourself and your allies in combat only, also with the trait active it neather affect Valor Trait VI Retributive Armor (gain precision based on your toughness) nor the quality maintenance oil (pve consumable). In the hero panel [H] the toughness adds up (displayed) but not the affected precision in both mentioned cases.

it’s an important issue in wvw, would be very nice if you fix it

Percentage based traits such as this scale off unmodified stats, and is treated in the same way across all professions. It’s not a bug sadly :’(.

no, you r wrong

borderland bloodlust is taken into account as well as defense against guards

Ok, in terms of in combat or boon related modifiers, to be more specific..

so it s a bug and has to be fixed, thanks!
