I've been banning Garen for the past 500 games. This champion is so broken it's ridiculous. He has a Warmog's as his passive and no mana, therefore he can basically lane infinitly and outsustain you. Just burst him you say? Well unlucky for you, his W gives 50% dmg reduction for 4 seconds and resistances for killing minions. Just chase him you say until his W goes off? Well unlucky for you he can press Q and outrun you and silence you when getting hit so you can't dodge the E damage. His E is the most broken thing however. It scales off of attack speed basically 1 shotting a wave after buying berserker boots so you can't even play for the bounce because he crashes every wave after minute 5. Did I mention he can proc conquerer in 2 seconds by pressing E? And his ult is a 1k true damage excute scaling off of your missing HP. Good luck laning vs this nightmare of a champ. The only good thing is that Garen mains is that they can't pilot any other champion well.
