Well. Since people think Elo matter that much I'll also state my opinion about him. I'm kinda an "average player" being around silver 2/3 for a while.
I remember before the rework I used to say to my friends something like "If you top and are a first pick, Garen is the way to go" Mostly because is passive is stupid broken when you have a
and since you build a
on him...I always went full tank on him with a black cleaver and sometimes an infinity edge as a last item if our damage dealer were too behind. I nearly always was one of the biggest damage dealer to champion. Mid/Late game, when you back you probably have around 2500 gold because you are ALWAYS full life. If you haven't be killed, dance for 6 second and enjoy being full hp....
Now, about the rework. Yes, his Q last for a less big time, but what was making him at least "strong/op" was his passive with warmogg and spirit. I have no problem with resourceless champ. But resourceless champ with such an incredible regen power is....ugh. His ult used to be what I call a "ks ultimate" a.k.a "Finisher" but now...I played him, played against him and, no joke. Ult the villain when he is around 50-55% of his hp and he dies. At this rate it's not even close to a finisher, it's a point and click Zed ultimate combo perfectly executed with true damage.
Kiting him? Slowing him? You take swiftness boots and with a full defense mastery you just do not give a ****.
Garen lost some utility, but he also lost his biggest counter
, the itemisation (especially the new one) make him so easily powerfull.
Oh, you lack movement speed? We have a thing for that. What? You want to regen faster? We have 2 good item to synergise with you
. Oh? You want to shrek the enemy armor in 1 spell?
Time . Oh, you want some damage?
. Getting kite?
.Which I have no problem with. But he is so good at long term fight because after 3 to 4 little fight were both team lost HP, He will be full and OS one guy.
Even Mundo looks pitiful looking at Garen and this guy actually spend HP when he uses a spell. Yes, Garen regen isn't that good when you are in fight. But you don't need to regen. You are a tank who is certainly full life at each team fight, late game.
Have you even tried to siege the enemy team at their last turret with him? It's a poke fest. But Garen will and always will be full HP after 4 or 6 second. Poking him just so his heal doesn't happen every 4 second is a waste of mana/Cooldown.
I don't think he is freelo, but either his passive or his ult need to be lowered. Because a 4 second cooldown on a passive with such a big regen power is anything but balanced to me.
