The Way LCS Works Is Almost As Stupid As Eliminating Solo Queue
Just like DQ tells you nothing about a player's queue configuration (despite how different the skills can be) for what was achieved (solo or only 5-mans etc.), the LCS standings are pretty meaningless. Let's take Immortals for example, they go nearly undefeated in the regular season but lose a B05 and are eliminated from going to MSI. Streaks are not uncommon in LoL because the game has a lot of unpredictable factors (RNG, someone escaping by just a few HP, a ward giving critical info. or allowing a surprising pick, etc.).
One B05 shouldn't be more important than the regular season's performance. It's just as stupid as promo games and isn't an accurate reflection of which teams are best. Every time a team beats another in a B05, the casters act like it's some conclusive proof of which team is best. That's just nonsense and I'm sure they're not dumb enough to believe it so it's probably just for show/hype. It should work a lot like in tennis or chess with something akin to an ELO system. Every win/loss should matter to the placement beyond just seeding. It's such a stupid system atm and so unrepresentative. 3 games shouldn't matter more than something like 20 games in the regular season and shows that Riot cares more about artificial excitement than an accurate representation of which teams are strongest (just like I guess they don't care about their in-game ranking system's validity since they clump every queue configuration into a single rank).
I don't even care about Immortals, TSM or CLG. I'm more of a C9 fan but I think Immortals was clearly the best team overall this season in NA regardless of losing to TSM (that Lucian top OP). CLG's an excellent team but there's no way it makes sense to judge them or TSM as better just because Immortals lose 3 games in a row. Hell, SKT just lost 4 games in a row at MSI and I doubt we now all think SKT is worse than Flash Wolves or CLG overall.
