Riot encourages selfish play

So this does not apply to premades as much as it applies to solo players.

Too often the player on my team that got an S was the one that took most of the kills even if I contributed with an assist, or the player I died to save so they could clean up the teamfight.

The hextech system by requiring players to get an S rating for a chest rewards greedy play, taking all the kills, cs, and other last hits -- even stealing farm from other lanes.

In addition it encourages never doing anything that risks a worse kda, like taking out a high priority target. Even if it makes you lose, as long as the early game gave you a decent KDA then playing passively into a loss is often more likely to give you an S than if you try to win. Sure you might occasionally try to pick off somebody that might be out of position, but rather than risk getting picked off yourself going back to afk farming rather than pushing might just be the better decision if you care about the S more than winning.

it is double standards at its worst. A solo player not in a premade doing everything to win, even if it means sacrificing themselves for the team by taking out a high priority target might not get an S because they died, despite making the right decision.

If your goal is to get an S for a box, then even losing on purpose is better than winning without getting an S, because if you lose then your MMR drops and the next game you might have opponents with lower MMR that you have a higher chance of getting an S against. The system as it is literally encourages losing on purpose or surrendering if there is no chance for you to get an S for this exact purpose.

Possible solutions?

• One is to remove the restriction that your premade has to get an S, as long as anybody on your team does
• This might perhaps be a bit excessive, so a second solution is to only require an A (or maybe a B) as long as another player on your team gets an S.
