CC in plenty of other games does fine with mini-elite enemies being affected in some way, somehow. You're having trouble understanding why CC frames having defacto deficits in their kit, by design -- versus other frames without that disadvantage -- is a problem.
Frames like Banshee and Nyx are jokes, with usage rates reflecting that. Limbo and Vauban are increasingly worse off. May as well give them each a new version of Mesmer Skin, since you believe that it's the pinnacle of active gameplay.
Truth is that it's not a CC player's problem to figure out how DE should be detecting AFK play, but if all CC is inherently incompatible with DE's capability to combat AFK issues or "lazy" gameplay, yank it.
Let's all be glorious non CC frames.
