Guild Wars 2

I have a problem with stealth of other player. When they should reveal i only see the effect of the stealth finish but they still be invisible for about 2 seconds and this is really annoying expecially in pvp. Here there is a link where you can see what it happens http://www.youtube.com/watch?v=AOdHJRvkVlo&feature=plcp.
Is this normal? my friends say no.
I want to know your opinion and what i should do to solve this problem.

Seems normal to me :s I think a thief also has 3 stealth cable abilities. Heal, Steal and dagger 5

I honestly don’t see a bug in the video!?

@blue: And also multiple utility skills + passives from traits.

Do you say that is normal that thief can do two attack before they get visible?

Yes, i think so, I’m not sure of combat break stealth? With it only being 3 seconds are so. Also with thiefs being squishy (lowest health pool) out of all, it would some fair, as when a theif has done his burst, or applied his bleeds/poison – he’s pretty much useless until CDs are done, so that gives you a chance if they’re not slippery
