Positive Incentives
There are currently no incentives on being a player with a positive attitude. The current rewards for being a positive player is an annual gift around the winter holidays or if a wealthy player in your match can spot your a random skin gift. As for players with bad attitudes in the game are only reported towards a system that hasn't worked for 2 seasons until this new system comes out in the next patch. Still the problem remains to where only players of poor behavior are the ones treated differently. Countless accounts will either get banned while they continue to grow through smurf accounts. There isn't much of a reason to even keep your account if the only value on it are skins that can be purchased on any and all accounts that are legible. Furthermore, many of the modern skins today are already outstanding for their price points at 750RP, credits to Riot's artists. For some players that isn't much to lose and isn't hard to replicate onto another account.
Maybe Riot could further improve the honor system? When you lose and your opponent tells you that you played well and honors you in the end it feels good to know that your talents were recognized and could be improved upon. Instead players everyday are going through, "gg ez noob suck mid lane feed no re." Spam laugh spam laugh spam laugh spam laugh spam laugh And when gaining honor can give you a slight boost in IP? I'm sure that example has been given before plenty of times. But what if you were to halt the IP gains? And increase it drastically when with a party and the honor boost.
I'm not so certain where to with all of this except for the fact that player positivity needs to be recognized.
