I feel like, rather than putting all stealth under the same rules, you give it three tiers. One, breakable, which is like Evelynn's and is removed upon taking damage. Two, fadable, which has, well, the fade mechanic. Three, true stealth, which is for the short stealths that would really lose all meaning with fade, like Vayne's enhanced Tumblr or Wukong's clone thingy. All of these would be countered by True Sight - which is still granted via champion abilities - but some would be more reliable against high-AoE team compositions.

For example, the fade thing sounds fine with Akali, Shaco, and similar champions, who either keep their position obvious or can easily use that stealth to travel a mile without being spotted. Meanwhile, if the enemy team picks, say, a Vayne and you believe they'll be a problem, you'll have to decide if you want to pick Corki, Kog'maw, Warwick, etc. to be able to nullify her stealth advantage or go with others that work better with your plan and just try to make sure she doesn't get to use that advantage.

Just some thoughts. I'd be perfectly fine Teemo shrooms and Shaco boxes appearing when you're close by but not with them deactivating. The former allows them to still remain a theat outside of brushes if you place them where line of sight will screw with your opponents, but the latter just seems kind of dumb. They already know they're there, why should they not be forced to avoid them? Especially since they could just bring in a ranged teammate and clear them effortlessly. It'd be kind of like only being able to place Nidalee or Caitlyn traps in brushes - literally, the game declaring areas not in brush to be invalid targets for the abilities.
