Defensive summoner spells and the return of Stifle

For those of you who are unfamiliar with the summoner spell "Stifle" here is it's description,

Effect: Silences a target enemy champion for 3 seconds, and removes any beneficial buffs they have.

Cooldown: 150 seconds

I'm a support main myself, and with upcoming removal of atk speed reduction as well as the armor/mr dent, it's (in my opinion) an understatement to say Supports and/or Mages are in serious lack of defensive summoner spells, specifically to aid others. When I say to Aid others, I mean that there is a staggering difference between , and I would classify all three of these spells as "Defensive summoner spells" but only one of them can be used to help fellow summoners who are in need.

I'd like to open a healthy discussion to the idea of a new summoner spell that has focus of giving the Support roll more variety other than MS/AS reduction.

Let's get back to that discussion on "Stifle" I believe most of us would agree this is simply a summoner spell that would be game breaking instead of game enhancing, but what if we tweaked the stats a bit? Below I will propose 2 options for a new and Improved Meta friendly "Stifle" using 2 pre-existing summoner Icons to help differentiate them.

Stifle

Effect: Silences a target enemy champion for 1/1.5/2 seconds and reduces Armor/Magic resist by 10/15

Cooldown: 210

Range: 700 Units

Stifle

Effect: Silences a target enemy champion for 1.5 second and depletes 10% of targets current resource pool. ( a pool of 200 mana/Energy/Rage/Fury/Health would result in having 20 removed, a pool of 2000 would likewise see 200 removed)

Range: 700 Units

Cooldown: 210

The silences (at such short duration) seem appropriate for champions that also have similar Team fight swinging abilities within their kit such as

Let's discuss healthy options to a team oriented defensive summoner spell.
