RP Through Matches

I understand that RP is Riot's way for players to buy things in-game through IRL currency, however what if you could earn RP from matches? Not a lot, just a little so hear me out 1st.

You get RP based on your kills OR assists (whichever is higher) minus your deaths. This means say you go 8-2-7, because your kills are higher than your assists you'd start with 8, you died 2 times so you would lose 2 RP giving you 6 at the end of the match. 8 kills - 2 deaths = 6 RP gained kills/assists - deaths = RP gained Note that you won't lose RP if you go negative like say 2-8-7. 7 assists - 8 deaths = -1 but it would just stop at 0 RP gained so you don't end up losing any that you buy.

This is just a thought, but I feel like this would make players be more mindful of how they play the game and want to make smarter decisions (like say ward, watch mini-map more, actually be helpful to the team, etc.). Possibly also have you earn half the RP gained if you lose the match rounded down (so lets say you earn 3 RP, half of 3 is 1.5 so you'd gain 1 RP instead of 2)

This would also give players who can't buy RP access to the things players that do can.

Let me know what you think down below about this.
