Several thoughts.
First, someone griped about the "Unkillable Demon King" nickname. Yes, it sounds a little silly, but when you have a completely insane highlight moment in a Korean final between the Telecom rivals where he completely outplayed the enemy midlaner, he damn well earned that and you can't just take it away. If you haven't seen the Faker Zed vs Ryu Zed, go find it. I'm not a fan of the nickname either, but you can't deny he earned it.
Second, he is the best LOL pro, period. Go back and look at who the other top Midlane players were in Season 3. Now see if any others are still playing or even on a top team. Part of what makes Faker special is how long he's been a top name, though numerous metas, having played and beaten the best using assassins, mages, caster supports, and tank supports, even taking an occasional Olaf mid to style on a poor IWC player. He's not invincible, but there hasn't yet been any other midlaner who comes close to his sustained success. Naturally at times because of all this, commentary will be focused on what he can do opposed to what an opponent does.
That said, a caster comment when Faker gets melted by a fed Draven like "Faker can't do anything because of the Bloodthirster" just as easily lets you know the other guy did well. I mean, do you need a caster to break down the axe catches by Draven? When the champ doesn't offer a skill outplay that can be broken down, and clearly can steamroll thanks to a sustain item, what else do you expect the caster to talk about?
Other follow up comments...
Way to cherry pick Game 3 World's 2017 at 33 minutes. Too bad at that point Bang already threw, SSG got Baron easy as a result, and because of Ardent Censer meta and SKT'S ADC twice being a tard and feeding left Faker with no choice but to survive and lose or die and probably still lose but at least you tried something. This specific choice only shows hate for the player and absolutely zero context for the play you're criticizing.
And then talking about that G2 match where Kahn kept getting caught repeatedly and casters kept praising the Pyke, Jankos ganks with Jarvan, mentioning Caps roams....oh wait, they barely were talking about Faker that game. What's your beef?
Someone else already spoke on top laners and junglers for SKT. Frankly they should have ditched Blank long before because he was horribly inconsistent. Most players left SKT after getting a trophy hoping to be the star on a new team and get a payday. Look at Impact. Marin and Duke follow that mold. Peanut only wanted an international trophy. None of them have faulted Faker or casters, why should you?
Someone commenting on Rookie crushing Faker "like a bug." Let's be honest for a moment about that champ select...Irelia against Ryze in mid, and that pesky IG Camille jungler factor too...you want to make this about skill when clearly the draft wasn't meta picks from SKT?
I understand fatigue, but seriously this hate train is silly.
