Guild Wars 2

If you have played pvp you can understand my hate for thieves and mesmers who can become invisible with an advantage that other class can’t have.
Stealth is a primary mechanism for thief but it is overpowered for me.
I don’t say to remove it but to give to the other profession some tool .
Example : the bonfire skill from the ranger’s torch can emanate a radius that dissolve stealth, in this way thief can do ambush but in combat you have a tool to understand his position. What do y think?
