There should be more incentives to play Normals > Ranked

Give players more IP per game in Normals.

Why? Because it gives incentives to players who aren't competitive and have the entire set of game knowledge to play Normals. And maybe after unlocking all their champs / runes (tools) they need to succeed then they'll play ranked better when they're ready for it.

EDIT: Okay, to clarify incentives. They work on a double edged sword, they reward players who play well with points and also attract players who aren't necessarily playing for the win, instead they're just playing to play. A casual ranked player is what I call it. You're in bronze - gold but don't care, you don't really play objectives you're just having fun, theres nothing wrong with it but it goes against the majority of players in the ranked environment. The reason they're in ranked games is because Normals gives them nothing more than a ranked game would, actually it gets less. (You can't get a skin / player icon and you can't get LP ranks)

If You give players who are casually ranked queueing an incentive to play normals then overall levels of toxicity would in effect go down. Theoretically. Would this help? maybe, maybe not. But Increasing the IP gains in normals doesn't affect anyone negatively. (we're talking 20% more IP nothing ridiculous)
