I think the biggest reason for the toxicity is how climbing works. You can spend a few days playing to put a few wins together only to lose the 2 games that matter for your climb, latter would work much better with a hots style climb where you rank up after reaching the point total, similar to tft ranked. In my opinion why this would be better because it puts more power into your win streaks and would more accurately represent your rank. On the flip side no demotion shield might actually stop boosting since you couldn't just sit at d4 0lp playing one game every 2 weeks, I feel this way because 2 losses should not be more powerful then 10wins but that's the league we live in, latter is counterintuitive and punishes you more for losing then rewards you for winning. Wins and losses should have equal effect
