Guild Wars 2

Just want to know if this is working as intended. Channeling skills auto lock and stays locked on you until the animation is finished. No amount of stealth or evade cancels the target lock. So is this working as intended?

This is the end of animation

Yeah i think this stupid, if you stealth they arent going to be able to land the rest of their spell on you. But thats just how it is i guess.
