I made this guide for a friend, however you can check it out, this is mostly for fun as garen is stupid tanky and can dish out alot of damage.

This Build isn't really great for ranked, sometimes it works, sometimes it doesn't. Reason being, meta is different from Casual.

This Garen build can be VERY good for teamfight, as he will just shred people, but you won't last too long, as your W will only last for a bit, and once that is out, your kinda ****ed.

PROS: You dish out ALOT of damage, and early game, you can bully people outta lane pretty quickly.

Anyone that touches you is pretty much dead.

It's bit harder to kite you since you will be running at the speed of sound.
CSing is much easier (if it wasn't already) with Garen.

CONS: If you don't get fed or do at least ok in lane, this build will fall apart.

Darius can bully very easy due to him doing more overall damage. You won't have the greatest time with Darius, but you can still win due to your ULT being better in the 1v1 if you kite him a bit.

Your W is what keeps you alive and tanky, if that runs out and you're doing a 1v3 it best to run outta of there.
