Who the hell thought ADCs were in need for buffs?
I mean... seriously, think back. Whenever we were talking about "League of X" we meant that X champion Type was good and most likely both teams in every game had one. League of Tanks was when tanks were good and every team had one full tank, for example.
Now think back. Which was the ONLY CLASS that never cahnged? Top changed, jungle changed, Mid changed, Support changed... Carry never changed. Since a Meta was formed, EVERY SINGLE GAME had 2 ADCs. Some even 2 when Varus or others took the mid.
The whole game has ALWAYS BEEN the League of ranged AD Carries. There was NEVER an alternative. (except for Mordekaiser, but they had to do that by making him broken as hell...)
And NOW? Hell, ADCs are so stupidly overpowered, that 3 in one team still make a great Team setup. You can have ADC bot, mid and jungle, and dominate the enemy team. Its even a better choise than most others. Who was the genius who thought the ONE CLASS that was always so strong that you had to have at least one in your team, was in need for INSANE BUFFS?
