As a low ELO player, the new season terrifies me.

Low ELO already has a massive issue with people copying pros and not knowing why. Think E max build Seeing his LCS play EDIT support support etc. Now imagine that but with mages being played bot lane. If riot continues to support bot lane mages, then LCS will adapt. LCS(or even just diamond+) players have specific reasons and strategies to doing things. When people copy them in low elo the chances are that they don't understand the fundamental reasons for that build. E.G. Certain players would E on Nasus for the lane pressure and waveclear power, but most people who would copy the build don't see the gameplay strategy. What they do see is "Master 1 player-80% winrate on nasus. Skill max order E W Q", so they try it out and fail because they don't adjust their playstyle and end up losing.

If mages shift to bot lane then this issue will be seen constantly. for a while, at the least. EDIT: Not that the complaints of low elo people really matter. We are low elo after all.
