As a Mid Laner, I feel Like Bot has More Impact on Games
So I almost only play Lux, so my perspective is mostly from a mage like Lux. It honestly does feel like the meta favours bot lane. The Jungler goes bot to help them snowball and I go bot to help them snowball. If I'm ahead, there's almost no reason to roam top. The only times I roam top is if my enemy laner goes top, or the top laner is fed enough that we can siege their tower (probably) after I've gotten mid tower. Otherwise, I always go bot. Bot seems to fall faster and lets our adc come mid to take my tower.
Lost games for me, more often than not, are when my bot loses tower early and the enemy bot comes into my lane. Likewise, easy games are always those where the adc gets their tower early and comes mid. It's like the "4-man bot" is always gonna happen, you just don't know when and by which team.
From an ADC perspective, it might seem like the jungler is impacting the lane because the lead is typically off a gank. Or it might feel like a support match up, but to me, a midlaner, it just seems like whoever's bot gets an early lead wins. We gank bot to get bot fed.
And when playing from behind, it ALWAYS turns into a game of "stall until my ADC does damage." I am always reliant on the ADC. Even if I am fed and keeping the game going with a behind ADC, it's always so that the ADC eventually gets items and does damage. By late game, I can't kill tanks. Who kills tanks? ADC. By late game, I cannot siege towers, who sieges towers? ADC. By late game, we need an objective to push out from our base. Who takes Barons and dragons faster? ADC.
The game revolves around this role. My job is just to kill ADC before they kill my ADC because the ADC is such a huge chunk of the physical damage. Better ADC seems to be what shifts the tide of:
-Whether it's an easy game -Whether we win late game team fights
The games are so much easier if your ADC gets the lead in their lane. Games drag on so much longer when it's my ADC who is behind. A snowballing ADC just seems like it shifts the tide of the game way more than my being fed. If I'm fed, my job is just to make it easier for my ADC to get back into the game. I never feel like I can solo carry as a midlane mage. It always feels like I stall the game until the ADC can do their job. If the ADC never gets back into the game, it doesn't matter how ahead I am.
(It's quite hard, because zoning the enemy and getting a 50cs lead means nothing, but it's not impossible to be 10/0 by minute 15)
-And you can pick lategame mages that have carry potential comparable to adcs

now, so that the infinite scaling can (counter/supplement) my (infinitely feeding/fed) ADC.
