New Summoner Spell Idea

Some champions have a hard time peeling themselves. Vel'Koz comes to mind. Also Jinx. There are many others, but in general, I'm talking about squishy casters and ADCs.

Now, there are only a few summoner spells that help peel. Flash is one. However, this is both an aggressive and defensive ability, depending on how you use it. It lets you get out of a fight, finish off an enemy that is out of range, or engage.

Heal is another that is taken, but it's just some health and a small speed boost. If you've been hard-engaged on, it isn't going to help you in the same way that flash will.

Barrier is also pretty good against burst, but again, if they're all on you, you're dead.

Here is my idea: a summoner spell completely dedicated to peeling people off you, and letting your team follow up and get them off you. What it would do is cast an AOE knockback to everyone in melee range of you. Think something like the range of a Tiamat or Hydra active. The knockback would only apply to people in this range, but if they got caught in it, it would knock them back about 500 units or so. This would be great for an ADC or squishy caster that got jumped on by the entire enemy team, like Kog'Maw. He currently has no way to deal with this besides his Flash, which is down most of the time. The peel you created would allow you to back away and have your team continue to peel for you, since now the assassins or bruisers have been peeled off you.

What do you think? Comments? Suggestions? Criticisms? I want to hear.
