Adcs are becoming so irrelevant that they are being replaced by mages bot lane
Ziggs does what one the stronger adc does (cait) but better.
Meanwhile on this forum : "NERF CAIT TWITCH VAYNE SO OP OMG."
Its obvious that nobody here wants adc to be playable class, they want every adc to be as bad as kalista/jinx/sivir/ashe/etc are right now, so instead of suggesting solutions so other adcs can also be as good as the better ones they want the class to be shit tier.
If you nerf cait twitch and vayne further ppl arent going to start playing ashe or jinx, they are going to play cass, ryze, veigar, zyra and azir as the bot lane carries, in fact double mage combos like zyra + brand already crap over almost every adc other than cait and ezreal (they actually destroy those 2 aswell its just that they can actually farm against them atleast).
