I hate the new rengar ult.
So much fucking counter play in it makes it meh. first off you know exactly when he ults. You know exactly whos hes close too. And you can fucking see him when you get close. It also has a long ass CD.
Why does he need all 3 of those.
Old Rengar was so much more fun.
TL:DR: nerf twitch, better stealth mechanic.
