Bring back the Stifle summoner spell!

Lately we've had summoner spells removed, but never replaced. Revive will always live on in my heart. I think it's time we got some new ones to spice things up a bit, or even bring back old ones and see how they do in the current build of the game.

I'm suggesting we bring back the Stifle summoner spell in an altered state. The Stifle summoner spell did the following effects with a 150 second cooldown: Silenced an enemy for 3 seconds Dispelled all bonus effects, including red, blue, and baron buff.

What I propose on how this could be brought back and be balanced: Silences single target for 3 seconds Disables all bonus effects for 3 seconds. (Does not dispel effects, but instead freezes their bonus for the duration) 180 second cooldown.

I understand replaced Stifle originally, but it does a completely different effect. Being able to bring both these spells would make single target assassins even more spooky, as well as allow counter play to said single target assassins.
