Broken Champions and Broken Items
Champions Nautalis - 4 Different forms of CC, ungodly tanky, gap closer (his Q) Ekko - virtually unkillable, can build tank or damage and do massive damage either way, multiple gap closers Ryze - Notice how is pretty much a 100% banrate on anything plat +, point and click 2 shot ANYBODY Soraka - Do I need to say anything? Master Yi - Do I need to say anything? Lee Sin - Most mobile, infuriatingly snow-balling champ ever, and no matter what riot won't touch him Zed - Annoying, unkillable, too mobile, free harass and too easy to Cs with
Broken Items Rageblade - Build it on anything, win Gauntlet + Sunfire - Build on anything and win Devourer - Need I say more?
Riot has a team that balances things? Really? LOL.
Anyone who disagrees with these, well... Is probably Bronze or has virtually no clue what is going on in this game.
