Summary of Gnar Design
let me introduce to you a champion designed to win 100% of the time against bruisers, not 99% but 100%. We gave him multiple full tools as a ranged champ we don't even know why. He already have 400 or 500 range which is a huge adventage in league but it's not enough. He also has a 35% slow on 1 or 2 seconds in late game, or without cooldown if buys frozen mallet. His "Hyper" gives him 30 / 45 / 60 / 75% bonus movement speed every times he lands 3 hits, 2 hits if he uses Q Teemo couldn't kit people enough, we needed something stronger against bruisers on top of his hop, Ekko is giving people troubles because of his slow+bonus ms but gnar? it's fine i'm telling that to you. What is also fine is him dealing 14% of your hp as magical damage with his "Hyper" that way if you buys armor you're also fucked up, if you buys hp you're even more fucked up
He's a ball of stat with in built attack speed steroid higher than pre-rework tristana HOP ATTACK SPEED: 20 / 30 / 40 / 50 / 60% 5.5 - 99 (based on level)% attack speed from his passive, we made this so he doesn't even need to build offensive items to destroy people why would he? he can just build 4 or 5 defensive items and press E to deal 180 (+ 6% maximum health) this is like 400 damage if he has 4k hp, it's only 20% of a squishy hp, i mean we nerfed shen because we wanted this dude to choose between offensive and defensive but we shouldn't say it, The dude is INNERTLY less tanky than mega gnar since gnar has like 1k bonus hp from his passive, and 40 armor/mr.
But you thought that this was all? no, if this was all Gnar might have fallen on teemo's level, being useless in teamfight. We needed to give him an amumu lvl of teamfight. With his 1.5 seconds AOE stun, a brand lvl of AOE damage and his ulti brings knock backs, even more stuns.
this summary is too big, let me rephrase it: we made a champion able to fullfie amumu's niche and whoever's niche at destroying bruisers. oh and we made him manaless cause ****you.

after the 10 min mark.
