Tanks

Not only do some of them get ALOT of health. But they also get to have a shit ton of damage. How do you get past a Garen who is fed. can basically 1 shot you with His ult, has an Ocean Drake with Warmogs and His passive. And when guardian Angels pops is revived at almost half health....pretty much unkillable without the whole team on him. But once you go to get to the back line he turns and 1 shots you with his ult hits q silences you and spins one you.... how is one tank allowed to have so much power right now.
