Guild Wars 2

I think a cool skill or ability for thf/eng would be a camouflage skill for thf and elixer for eng that gives a temporary disguise like the ones used in pve.

the thf skill would let you take the shape of an in world object related to the area you are in , so if youre in a keep it could be a barrel. out in the open you could be disguised as a tree or rock, the skill would break if you move.

for engineer you could take the form of local wildlife akin to the mystery tonics. so you could be disguised as a doylyak or a hawk. the ability would break if you attack or use any other skills or abilities.

I like this idea any new suggestion to make engineer a slightly different is a welcome in my book. I support

Thief should have had camouflage instead of invisible skill.

Oh ye! you forgot the class thats a natural for camouflage- Ranger!
