LOL at this!
No other champion can match his durability, sustain, mobility, damage (not to mention mobile damage)
Durability: Yea he prob has one of the best durability.
Sustain: Very poor until lvl 16, easily out sustained in laned vs people like hec, vlad, mundo (pretty much any one with built in sustain) Once he is 16 he has the best sustain OUT SIDE of combat, in combat his sustain is shit. So if you can get away you can come back into the fight with full HP in a few seconds (this is why i love split pushing with him rather than team fights, cause I can ingage on some one then run away and get back to full HP in a matter of seconds, then do it again. This is VERY hard to do in team fights.)
Mobility: You are kidding right? no other champ can match his 1.5 sec 30% increase in MS?
Damage: he has alot of AoE DoT. ALOT. BUT he by no means has more than other top laners like, hec, shy, vlad, rumble. Specially when it comes to team fights.
And yes Garen can disrupt the enemy assassins/mages IF he can get to them, which in team fights is VERY hard to do. Do you know how easy it is to stop a garen from getting to you? any form of CC even a small slow can completely stop Garen from getting to you. Yes his Q removes slows, but if you dont cast Q to gain the MS buff then you will never catch them in the first place. This especially happens in team fights, where just about every one has some sorta slow, You cant cleanse them all with Q, meaning it is very hard to get to priority targets with Garen.
If Garen's building properly and using his W properly, it takes like 2-4 champions to lock him down.
EXACTLY! this is why he is an amazing split pusher. He forces 2+ people to come stop him and still able to get away, allowing your team to fight 4v3 or better. And what is better? a 5v5 team fight or a 4v3 team fight in your favor?
Just because he can't stun the entire team with one ability doesn't mean he's a shit team fighter
He is a shit team fighter because he can not peel for the carries, he can not engage effectively, and does not do enough burst damage, yea sure he can soak up alot of damage, if they attack you. but it is easy for there supports alone to peel a Garen off of a carry. Allowing the carries to focus down priority targets first.
