1: "Korean PC bangs are not representative of the world population." Korea (namely South Korea) has a relatively tiny population, but I believe some of the highest per-capita of PC gamers compared to everywhere else. It's still not indicative of the grand scheme of things.
2: Just because League is no longer the first (which they still are) doesn't mean it's a death sentence.
3: Much like the enemy getting first blood or a new champion coming out and being declared overpowered immediately, you, like so many other people on the forums, aren't waiting for the dust to settle. People flocked to Overwatch because it's new at the moment and just like League EVERYONE LIKES TO TRY THE NEW SHIT. Even after the bleed back occurs and people decide which they like more (which by the way, you CAN play more than one game), that's still not the death sentence of League people want.
4: This just means League's overwhelming popularity streak has fallen below 30% (in just South Korea, mind you!), much like someone finally killing that fucking 20/0 Zed.
5: I'm starting to think that the League community is secretly a suicide cult at this point, given how eager and giddy everyone gets talking about League's inevitable death and hoping it'll happen next week, along with the general soul-crushing defeatism that lurks in the average mind.
