The Might of Demacia- AKA The Cancer of Demacia
Lets take a look at traditional meta's You have a Caster/magical glass cannon, they do lots of damage but IN TURN for that damage they naturally become easier to kill You have a Tank who is strong and hard to kill that distracts the enemy with either his body or with crowd control abilities You have a healer, AKA a support, that again is usually vulnerable to damage but trades that off for being able to keep the tank OR the caster alive or the... DPS, next you have the Damage per second (DPS) player AKA the ADC. They do high amounts of physical damage usually and again are easier to kill We have one other player in league called the jungle, they roam around the map applying critical pressure where needed, they secure objectives they are usually physical damage based but some are magic based as well. These vary a lot
NOW thats usually how meta's go for the most part. It's a simple way to balance the game, but in League we don't have this balance and I can prove it over and over again. For example---
---Lets look at 
Garen can 1) Take enormous amounts of damage naturally (meaning without items) so no need for a TANK on the team
Garen can 2) Heal himself by disengaging from combat No need for a healer (especially with
Garen can 3) Do a large amount of physical damage, comparable to an ADC/APC or DPS based champion especially with
Garen can 4) Silence key champions and can run straight through front line defenses
Garen can 5) Nuke for a huge amount of damage with his "R" ability, this doesn't affect other TANKS that much but It does affect other "squishies" Like the ADC and the APC who are the key component to a team doing damage. Obvious in their name.
and Garen can 6) focus champions that have high KDA (Kills to Deaths to Assists ratio's) with his ult doing TRUE damage that is impossible to defend against if it hits you (with the exception of
type of abilities)
Still looking at
, we also see that the common build patterns for
are primarily 1 movement based item 4-5 tank based items, and 0-1 damage based items. If you don't understand what that means let me explain.
is playing the role of tank, his own healer, DPS, and Assassin (meaning killing a unit extremely quickly in a "Burst" similar to DPS based champions except these types focus on killing a individual champion and escaping) All in all, you can't kill him, you can't defend against him, you can only focus him with your whole team or focus an ENTIRE TEAM COMP with heavy CC to counter him, or you can try and out run him (Unlikely) and get around him to the other 4 members on the other side.
Not to mention
is also one of THE MOST simple and easy champs to play in league. You can land/hit garen with everything you have and he'll match that damage with solely spinning. Champions like
are toxic for the game, they break balance literally.
A game in which players have to base entire teams to stop a single other player that has 4 other champions that you also have to worry about, frustrates entire teams.
People say, "well that's just the game" or "counter build him" or "out play him" which falls directly under the point above, any "1" champion shouldn't by appearance, force "5" other players to bend: champion picks, ability order, item purchasing, and team strategy. "1" single champion shouldn't have that kind of an affect on the game. It's the definition of "broken" something that is so unhealthy for a game is broken. This is the same reason why
is disabled for "one-for-all" match types.
ADC-easy to kill, high damage output APC-easy to kill, high damage output TANK-hard to kill, CC focused, low damage per second Healer-Low damage, easy/medium defence keeps tank or other champions alive through the fight Or have CC focused abilities Jungler-medium to high damage, low to medium defence, focus on map pressure
Garen- High damage, High defense, Self healing, Fast mobility, AOE damage, Nuke/true damage Ultimate ability, requires team pick counter, item counter, and heavy CC to defeat. Garen has everything every role is good at but none of the trade offs. Take a look at his picture in the League client, it describes Garen as having near the same damage output as ADC's but with 3X's the defense potential. League even acknowledges his power and no one cares enough to speak out about it. Lets get something to change to make the League community healthy again.

and his dashes, or
and her triple Q and E.
Oh hey, you came up to farm and now your passive is permanently nullified. Lulz.
