rengar still strong this season. but he still weak against bruisers. with this build only tanks with high *** cc can stop you. even if you're behind in cs, kills, objective just trust the process of the build. once you build collector the enemies are cooked. I advise just absolutely wrecking they're backline. even when they're frontline is low, I use that as a bait for them to drop their guard. always remember that a lvl 10 assassin can beat a lvl 18 mage (without cc, hourglass and good dodges) old school is always best.
