Rogue and Druid Stealth should have a 30 seconds duration on a 15 second cool-down.
Stealth should decrease the movement speed of players in PVP by 50%
For every 1% dampening, the cool-down of Stealth should increase by 1 second.
This means by 30% dampening, Stealth would last 30 seconds but have a 45 second cool-down.
There is nothing more toxic in arena then coming against a Sub Rogue who can 1 shot your healer during Shadowy Duel. then sits in Stealth and repeatedly lien of sights to stealth and your unable to do anything about it because the class is POORLY designed.
Stealth right now have ZERO down side. Casters have to cast and can be interrupted and line of sighted. Melee classes can be disarmed, Line of Sighted and kited.
Stealth classes. they get line of site of a caster, easy restealth. You attempt to kite them due to insane damage. they get restealth.
Even if you dot them. they can resealth. i know the stealth conduit is being nerfed but it should outright just be pruned and replace with a conduit that reduces the cool-down of stealth by 5 seconds.
anybody that disagrees with this are biased and either play a rogue/druid or play with one.
