League is being Competitively balanced around Casual Gamers? What?
Most people seems to agree that the introduction of dynamic queue, general 'watering down' of individual rank, and incentives to play with friends are all geared towards casual players. In every major patch though, Riot's motto seems to be "every choice you make could lose the game." With long death timers, specialty dragon buffs, snowbally itemization, and the idea that all champions should have clear niches to counterpick each other, there's almost no room for casual players in the actual gameplay.
If the target audience is supposed to be some sort of "casual tryhard", then it's no wonder there's so much salt in the league community.
