No but seriously, this season honestly feels kind of decided in champion select.

N0rth Wind1 votesYour team actually had much higher carry potential than their team. Vel'Koz, Jhin, Darius can carry super hard with a good team, Leona is the best ally for all 3 of them and Elise is an early game monster that is still a threat later on.
From the enemy team, yes, Shaco is a nuisance and Vayne is scary, but only her and Yasuo can carry, and he's not as easy to snowball with.
So yeah, unless you died 50 times to Shaco early on and Ziggs started taking turrets left and right, the team with the most carry potential is easily yours.
The enemy team doesn't even have a proper frontline- only Thresh is even semi-tanky, the rest are paper, and you have fucking Leona, Darius and Elise, assisted by the most powerful nuker ADC in the game, Jhin, and one of the most dangerous artillery mages too.
I literally fail to even imagine how you even lost those teamfights. Unless you got caught in a 5-man Yasuo-Ziggs ult combo, you and Jhin were left helpless against Shaco by your tanks and Vayne was dealing with Darius, it was an easy win.
Simply send Leona and Elise in first, bait Yasuo's wall, initiate on the backline, send Darius to either get a penta or just pressure the enemy backline, and you and Jhin murder Vayne and Ziggs from a million range. Only danger here would be getting hooked by Thresh at a bad spot or getting oneshot by Shaco, but that's 100% up to teamplay.
