Garen needs a rework (hear me out)
Garen, a champion typically directed towards and used by new players because of his low ip cost and the simplicity of his kit. The meta and the game itself has changed quite a bit, but not so much Garen along with a lot of the older and more simplistic champions like
Annie and
Cho'Gath.
Garen falls into the category of champions that I don't refer to as tanks or bruisers, but rather as a one man team. Just like
Cho'Gath, and
Volibear, who all offer cc, high single target and AoE damage, AND executes, all while taking minimalistic damage with incredible sustain (they aren't very hard to play either). Another champion that could fit this category is
Tahm Kench, although he doesn't have an execute, he still has very high base damage, high scaling ratios, and damage that scales with health.
These champions with only one damage item, such as
Black Cleaver for
Garen and
Volibear, and
RoA/Abyssal
for
Cho'Gath and
Tahm Kench, and then building tanky from there on out can feel like you're trying to kill a raid boss in the late game.
Anyways, back to
Garen, if Garen really is meant for newer players to help them learn the basics of the game, you should rework him along with many of the other simpler champions to help teach new players instead of handicapping them. Garen's kit is a bit ridiculous in my opinion. He has a passive
Warmogs, no mana pool, an auto attack reset that grants movement speed, deals bonus damage, and silences the target, a built in damage reduction spell, and an execute that can deal true damage. It's not just as simple as "It's OP" or "As long as they don't get fed", the players that get used to Garen and this kind of play style that offers so much utility, cc, base damage, scaling, and tankiness will handicap them while playing other champions with a higher skill cap.

Xin Zhao, and

I think that
Garen's kit can remain the same with some minor tweaks. I think that taking the silence away from his Q, and adding an interrupt effect and maybe even a slow if you wish, instead replacement of the silence. I also personally believe that the damage on his ultimate shoudln't be as high, or scale as hard as it does currently, and I say the same thing about
Cho'Gath's ultimate and
Volibear's W.
I think having an execute as a tank defeats the whole purpose of being a tank. You might think this would render them useless, but I think it would promote proper play within the game where the tanks would have to do their jobs as an actual tank and instead of looking for 1v1 scenarios without their team. Instead, they would have to look for a teamfight where they would have to coordinate their cc and engage with their teams damage and not their own. I think this will help promote the mindset of a team within League of Legends. League of Legends as we all know is a team game but often, especially in lower elo, isn't played like one. I've lost so many ranked games where we were winning but the team wouldn't group, eventually costing us the game.
Another suggestion I have, is to just go ahead and remove all silences and replace them with interrupts, creating an opportunity for player skill and outplay potential to shine, instead of just using the ability on cooldown. You've already removed most of the silences from the game, like the ones from
Talon and
Kassadin, but for whatever reason, not the longest ones that seem to have an even bigger influence on the game, like the ones in
Malzahar's, and
Cho'Gath's kits. Lets not forget to mention that they are both AoE spells that aren't very hard to hit. (meaning that they can strike more than one target)
I also believe that the scaling on
Cho'Gath needs to be reworked on his abilities and feast stacks. I also don't like how
Volibear's W, an execute, scales with his hp.
Now I'm not saying that these are the only and/or biggest problems within League of Legends, I'm just trying to help bring some balance to the meta. There are stronger things out there right now, for instance,
Xin Zhao, but overal he does fit his role with his kit as a bruiser/fighter (maybe a little better than he should). Xin Zhao if fed enough could 1v5 given the right scenario, but I wouldn't go as far as calling him a one man team. He does offer some utility with a gap closer, slow, and knock up, but at least he has to play a certain way in order to be successful. I'm trying to promote a more skill based game with higher potential for outplay and a team mentality within League of Legends. Please consider my ideas, thank you for your time.
If you could think of any other champions you'd like to see changed, nerfed, or buffed, please leave a comment mentioning who and why.
and even bruiser
