People dont understand how game changingly powerfull randuins on an ADC is
Seriously.
The Rengar ult that would have 1 shotted you does 1/4th what it used too. Assassin's literally become obsolete, and if the enemy team is all AD its gg wp.
Do not underestimate this shit, randuins/ BT on a full build caitlyn and diving her is a suicide mission. When you cant be bursted down, lifesteal becomes a broken stat. Think outside the box adc players
