Guild Wars 2

the description of the traits indicating a 100% chance of making a critical hit when leaving stealth does not work properly because not always does a critical hit

I believe this is a known issue. I’d check the bug forums.

i reported it a few days ago all the bug related to this trait^^ let hope it get fixed

They are working on fix. Not sure how long it will take though.
