Guild Wars 2

So right now I’m using an axe and a focus as a nec.
The focus is accursed chains, and used to provide +90 accuracy with an additional superior sigil of accuracy that came tacked on when I got it. It would increase my crit chance by over 5%, which makes sense as it’s adding a +5% chance to crit with the precision on top of that.
Then I transmuted berserker stats onto it but kept the sigil. Now I am getting about 3% chance to crit bonus from it and the sigil appears broken.
I slapped the same sigil onto my axe, my crit chance initially went up 5%, but after un-equipping and re-equipping the axe my crit chance dropped to where it was before, leaving me a bit frustrated.
It could be that these are providing an invisible benefit, but I really cannot be bothered to write down the results of a thousand or so attacks to get conclusive data on this.
The bug is either the crit chance not showing up or the crit chance not being there altogether. Either way, it needs to be fixed.

Seconding this, just put this on my weapon and critical chance has not changed at all.

Its a visual bug. It is applied but not updated on your info screen.
