Who cares the rewards aren't worth a damn anyways, not saying to be toxic just pointing that out that Riot's last stupid suspension because of being trolled by a role-steal and feeding, that I don't give a rats ass about the rewards...
The rewards aren't that great, you have to play over a million games to get anything worth while, and the only time it will be truly worth-it is when it becomes like DOTA 2 giving full items, and allowing trading...
Face it if Riot wants to reduce toxicity they need to work on better match-making players with competent players not stupid ones, same way in OverWatch when I just go into a random game I get idiots lose 90% of the games when I go with a pre-made group of players its esaier, match making needs to factor in other things, and Solo Ranked (Should not be based off WIn / Loss) but other factors that contribute to ranked as well and a persons personal score including K/D/R, CS, as well as other stats.
