I would like to state that stealth is not completely useless in PvE, as it is a perfect way to escape when you are out of a heal.
For instance; You are fighting 3 bandits after clearing out a den, you have 25HP. You tap 5 activating Cloak and Dagger, evade backwards and lay a trap of Ambush. After stealth wears off and you’ve made some distance away, they trigger the trap and are momentarily distracted. Meanwhile you’ve set down a Needle Trap. Sure you could have done all of this without stealth, but you would have been attacked for those few extra seconds and you might of died.
