So here's an idea that I've had for awhile...
Summoner Karma.
I really put a bit of thought into this and I think you'll agree or at the very least, enjoy what I have to say.
What is summoner Karma?
Simply put it rewards good summoners and is less forgiving on worse ones.
Okay, but what is a 'good' summoner?
Well, summoners with a ton of honours and gifted a bunch! I think you can agree with me one of the best feelings in League is getting gifted. Why not reward those who do it? Honours currently have no place in League other then to be taken away, summoner karma can fix that, and make League soooooo much better!
Alright, let's get to the good stuff. What can summoner karma do for me?
As mentioned.. Rewards! I imagine summoner karma being a number that increases through all the things you do in league, for example honours and gifting! Summoners with a certain karma level or higher can get rewards like icons or a mystery gift! But why stop there? What if you're a honest to good summoner who wouldn't hurt nobody no how - buuuuut accidentally got banned for getting mad a Malphite who fed until he's 0/9 when you're 2 points away from Plat promos.. Despite that being oddly specific it doesn't matter! Your karma takes the bullet for you if you have enough, but at a cost as it'll lower your karma. For summoners with already low karma, their bans will be more serious, as they should.
This way it'll reinforce the positive side of the community, and at the exact same time help push the negative side of it out.
