Over Hyping is the real problem of this game.
Over hyping something that is broken/weak has lead always to over nerfing/buffing which in return causes bigger issues to the overall balance. Naturally Riot always gives into the hype and they always over do it. Like right now OMG ADC SO WEAK when in reality adc arent even that weak id call em balanced actually , not being 3 shot by an adc feels great for a change ,but they still deal significant amount when the support does a great job to allow that to happen.
