ADC is so unbalanced since ADC patch.

If one of ADc is ahead at early game (cs, kill, gold, better ad item building, and etc) and they are almost impossible to be killed without any properly strategy... (assassin, surprise attack, stupid move, or even unlucky.)

They need to be tune down to mage/top power level.

Take a look at http://champion.gg/statistics/#?order=descend&sortBy=general.goldEarned

They are mostly ADC and crits-based champion.... see what I meant? ADC is more forgive to play and capable to comeback.... unlike Jungle and Support.
