League of legends has not even a safe lane anymore.
I know there is a plenty much post that say alredy that damage is high but I would focus more on another side of aspect: safe pick. Right now if you wanted to play a safe pick such a tank on top lane, you will get demolish by the enemy bruiser. If you want to play a post lv 6 champ such as amumu, you will be useless for the entire game. If you want to rely on a wawe mage such as anivia or malzhar (I hate place him as wawe clear mage but this is what he do now) you will lack the roam potential and most of the time you need to delay your mana item for getting a zhonya (because talon,zed,irelia are thing) or even worst a bashee (lb). Adc now is a mess. Even the safest adc is now not safe (hello ezreal) because they can be oneshot not only from assassin but even from bruiser and diver (camille and again irelia are the best example) that they are suppose to deal sustained damage but they end with an assassin damage, a tankyness lower than a tank but higher than an assassin and a mobility like sonic will only get. Support role is now in the panic. Adc has stopped to play adc and the safe support (enchanter) fell to much weak compared to poke support such as fiddle and brand or all in support (blitz alistar leona pyke). If someone want to play a ranked relying to a safe choice where you are sure to don't feed, well you will end feeding more than a risky choice such as bruiser or assassin. If you rely all in the late game, there is no more one because game end to fast for this and your safe pick will be 80% of the time be stomped by your opponent.
