Guild Wars 2

Hi guys, I’m looking for some help.
Anyone knows if these 2 traits are bugged?
“Flawless Strike” and the minor “Keen Observer”. When I’m in combat (I have 53%crit chance) when my health is above 90% I can’t see on stats the +5% crit chance.
Same thing for “Flawless strike”. If I switch to “Signet of Power” I have the same critical damage if I’d chose flawless strike. So nothing change.
Can anyone explain me why? Is it a bug or I don’t understand how they work?
Ty all!

They are situational stat buffs. As such they don’t show in the stats menu. However, though I haven;t tested in post patch, the stat boosts from flawless strike, side strike, keen precision are still calculated by the game during combat. So don;t worry, if you take them the game will be applying them (you just won;t see it in a menu).
