Guild Wars 2

When fighting karka’s as a thief stealth doesnt help much, atleast not to me it seems.
The karka’s keep targetting me, just turning around whereever i go, despite me being stealthened. this makes backstab impossible.
what is more, they sometimes still attack me!..

This is because the karka channel that attack, everything that channels before you go into stealth will hit you, in pvp this happens less often as with mobs.
