Iím a big fan of
league of legends, and I have played it for almost two years starting from mid S2. I always feel LOL a very interesting game and every champion has its features. However, I have witnessed the ups and downs of numerous champions during this period. I think Riot does a bad job on game balance: they neither let every champion shine nor keep the game balance regardless of some powerful champions.

S4 changes improve the playability of supports tremendously, but they still canít carry the team. Why? Because ADC is too weak. The bot lane has been in the unfavorable situation from S3 till now. Riot has highly stressed on the importance of top and mid lane and nerfed the bot lane. ADC is always been nerfed from champions, defensive turrets to items.
