Guild Wars 2

Because right now its pretty much a joke vs any NPC or player that has a “teleport” type of move.
I’m doing the map completion on my warrior and I’ve got the trait that applies 1 second of immobilize when I cripple a target, using a GS so when i throw it out it will apply the immobilize. Was killing Separatists when i tagged the thief class with it at max range (so he hadn’t aggroed on me yet) and the purple chains of immobilize show up on it. Yet he’s still able to shadow step or w/e to me.
This also happens all the time in WvW and mostly against Thieves (Surprise surprise), I’ll tag them with the GS 4, or axe 3, or sword 3, or use the Bola and all they have to do is switch to a bow and they can get away.
i’ve seen guardians, Mesmers (again surprise surprise), and Ele’s able to do it as well.
I really hope this is just some massive bug and not “Working as intended” because if it is thats some serious bull kitten.

Its called a cantrip or similar break stun skill. It basically means… You can’t be tripped.
