Garen Needs to be Nerfed. Period.
I seriously cannot fathom the thought process, or lack thereof, of allowing a champion like Garen (a natural tank) to have the abilities of true damage and the overall lane bullying he's possessed since the addition to his ridiculous health regeneration a few patches back. I encounter him in game quite often with a build that's best described as a hybrid ADC/Tank troll build with the usage of his regeneration combined with ridiculous damage to make a fully frustrating experience for anybody who's unfortunate enough to go up against him. Just for this discussion let's remember all the things this guy can do, shall we?
His passive allows him to regenerate health as long as he's not harmed by a champion/turret in a nine second period. Problem is, the amount of health increases every time he hits 6, 11, and then 16. Now, if you have Warmog's and you take damage from a minion it resets the amount of time for the Warmog's Heart (or the now "old" increased health) before you can heal again. Garen has no such problem with his regeneration, so he just heals while taking minion damage. And monster damage, later. This in and of itself is an issue since he's the only champion I know of who can heal while attacked by minions outside Galio's W and even that has a limitation.
Garen's Q: One single ability, with a cooldown of only a few seconds, allows him to break free of all slows, get a burst of movement speed, do bonus damage on his next basic attack, AND Silence the target. All in one single basic ability. The worst part, all of this is on a few seconds cooldown, max!
Garen's W: The rework to this makes it perfectly fine the way it is.
Garen's E: This I have a lot of problems with. His Judgment can critically strike, it does bonus damage to a single target, allows him to spin through minion waves and ticks of his sword can do true damage to a "Villain" in the game. Why the hell does a tank need to have a critical strike chance? And before the swarm of replies about how it is JUST one percent health true damage, each tick does one percent. Each basic does one percent, and then his ult does the ENTIRE damage in true. It all adds up, and frankly, this buff is not required for a champion already way OP for his role.
Garen's R: The only real problem I have with his ult is the true damage aspect, but even that could be bearable if it didn't increase in damage on the lower health the target is only because his damage is so ridiculous even if he builds one single damage item.
The most common troll build with him is an IE, Boots of Swiftness, Sunfire Cape, Black Cleaver, Warmogs, and one other situational item. This allows him to just kill ANYTHING as quickly as an ADC while tanking two or three people's damage in the process. But, rather than just post problems, I have a solution!
Reworked Garen.
Passive: - No more ridiculous health regeneration while taking minion damage, at all levels. He will heal for the same amounts as he did prior, but the level 16 and up regen is removed. So now he has normal tank regeneration, but the bonus healing does not apply on minion damage so he has to wait a few seconds. No biggie.
Q: Remove the silence and bonus damage. The way it is will be fine without those two items since a tank isn't designed to do massive damage and silence anything from fighting back at the same time.
W: Fine as is
E: Remove any critical strike chance and true damage, period. Keep it as is otherwise.
R: Remove -all- true damage/Villain aspects. Allow the increased damage on missing health, that's it.
Garen will still be strong, but he won't be the overwhelming lane bully he is now. I've seen Garen able to tank ADC damage and require an assassin AND an ADC AND a burst-damage mage have to beat him down because of his abilities to silence and speedily move out of the way everytime he's in a fight. Most people I talk to think this guy would be fine AS a tank, but he's able to use his kit and build as an ADC who can tank three people in a fight and that is just too much. Adding true damage is just a further slap in the face to the concept of champion balance, since there is none right now with Garen. You preach to us all the time about how you want champions to be well-balanced, so I ask you to look at the way this guy is designed and ask yourself if this is a well-balanced champion, period. I think we all know the answer to that.
