Its kinda amusing to still see Garen nerf threads still, even if this one just hides it.
The end of the day, people only don't know how to fight him. They rarely dealt with him before his rework and now that he is viable, they are being forced to and people can't seem to adjust it seems.
Since from my own experiences, Garen often loses top lane to anyone that can actually fight back, he is a sustain champion, if you don't allow him to sustain himself, he will slowly lose lane pressure. The only times I have seen Garen win, was when I or whoever is playing him is against someone that clearly showed they never played against him, they would always allow themselves to get hit by his Q and not even try to auto to make the trade even, and run away from him and their minions when he E's into you, when that is what he wants you to do, since he does more damage if you are alone.
But again, I mostly gave up on these threads, since his rework was more a nerf to him than a buff but people will complain about anything that kills them it seems.
