And also, how much does this vary as you go higher in elo?
At least in Silver 1, it feels like jungle has the biggest effect on the game. If your jungler shits the bed your automatically lose all objective control and map pressure unless one of your laners can roam efficiently and still be fed.
Jungle > Mid > Support > ADC > Top
Top laner getting fed doesn't impact the game what so ever until minute 20 Jungle can influence everylane for around 15 minutes and continue to be a dominant threat Midlane has the chance to be a secondary JG Support's can roam through mid-bot
Jungle followed closely by mid lane. If the jungler is awful and doesn't gank and doesn't apply pressure and in general doesn't rotate the map very well, its 100% harder to win the game.
Top lane with teleport
no such thing as "most influencial roles" if players are not trash they will carry
It depends on the stage of the game and on picks
Jungle > Mid are the best if you looking for early pressure and playing assassins/roamers
Top > All if you playing something like Jax/Irelia/Riven/Renekton etc..
Adc + Support > most of other roles , if you looking for scaling and mid game to late game power
And as for your Elo , the easiest way to climb is by playing jungle or adc duoing with support or Top lane something like Jax/Irelia/Renekton , mid is not the best option since most of champions there exist to snowball and can only kill 1 or 2 targets , can't really 1v5 or something , and the role is too popular that you will get Autofilled often so you can't one trick anything
Top, mid, and jungle can macro a victory on their own. ADC has to mechanically do so unless you're like Jinx or Tristana and really want to try that macro. Support better be great at multitasking, but their roaming and warding can decide games as well. All can technically win through mechanics and/or macro, but it's easier one way than the other for certain roles. It certainly doesn't make any role have an inherent advantage as much as it does the player and their own skill or knowledge.
Jungle feels prevalent because players don't normally respect a jungler exists in Silver 1 and get caught in precarious positions or faulty wave management. It is a very powerful role due to the potential impact that it can cause certainly, but Mid has access to the whole map as well with more stats than a jungler. Hence why normally your Mid-Jungle duo can roam the map best if your top laner isn't in an inherently good matchup. In this sense, Jungle counts as high impact because it can affect the whole map as a pivot, not necessarily always as a direct carry. As a pivot, you are still subject to the quality of your team to theirs, just that you have more autonomy over your decisions of pressure.
You'll play for top if you want to rotate around, it's a lot of macro. Say your jungler snowballs top but nobody rotates or goes for objectives. Then you're not very ahead and the enemy team has a larger chance of coming back. Not to mention, if you let an enemy top run rampant, the game hardly ends at 25 minutes unless your team is playing perfect. Their top is going to become a monstrosity that bullies your jungler and your top -- as well as forcibly pulls pressure to them while applying it. So, while a lot of the time it might seem the jungler has the most impact, it's really whose team knows how to pivot around their jungler or winning lane. This increases as you rise in elo.
Now, my highest is D4, so I can't speak for the highest echelons like D2+, but as you go up -- the jungler gains a lot more respect and their free ganking is severely reduced. It becomes a lot more macro and generally you want to support your win condition. This changes with each team composition and who you are up against, but the jungler has the highest influence on it as a pivot, alongside a lane that is considered the highest priority, or the objective which lane is nearest to.
Overall, the game is neatly (ideally) set in that mid, jungle, and top can be set by macroplay -- and bot can be set mechanically. But within all of that, the jungle has the opportunity to always apply pressure even when they're losing, and this allows them to pivot for any lane as a support for that lane to apply more pressure. Game is relatively complex to spell out, but a lot of it comes naturally when you've played enough.
tl;dr - Jungle is power pivot and thus technically has both high value pressure for a team and also less than you might think if your team doesn't know what to do with it. Mid can pivot best off of Jungle, so it usually handles right behind it as well as having high impact on pressure to open the map. Support and Top are in the same tier due to the ability not only to roam, but also pressure objectives and deep ward easier into enemy territory and provide TP pressure or backup at any point before becoming a powerful split pusher or ghosting carrier. ADC is ironically the lowest only due to lack of autonomy that requires peel and reliance on being fed. They cannot pressure alone without it, and thus are relegated to mechanically providing a win condition. In that sense, ADC is variable and can be the highest impact to the lowest. Probably why it is also the most difficult to balance.
Keep in mind, all the roles aren't linearly able to line up effectively. They have a lot of details and it is a team game. But in the best terms I can give you for an answer in a simple form (even though above is better for information), it would be: ADC > Jungle > Mid > Top/Support > ADC
Top lane decides games entirely by itself.
You have a 17/2 Ezreal? Doesn’t matter. Jax is 2/1 and stronger than you at all points.
You have a 88/1 jinx? Cool, that Camille with just a tri force just instant killed her.
You have a stupid fed ahri? Cool. She just got instant gibbed by a renekton.
depends on the game. as a general rule of thumb it's jungle because they roam to multiple lanes. However, what happens if every lane shits the bed? The JG can still end up carrying, but that being said you can't put all your stock in being able to carry as a JG every game. A lot of times the jg requires at least one lane that can react to ganks.
Mid or top can shut down their lanes so hard and get so far ahead they will be able to end the game by themselves.
JG can do that too, for multiple lanes even, completely by themselves. Only difference is that your team started off in the lanes, and it's possible they could feed the enemy team before you ever make it to them.
That's the main reason I think carries at mid or top have a bigger impact. They can start dominating their lane from the very beginning, while jg sacrifices their early lane presence for map-wide presence.
Also it's best most of the time for the jg to stick to one lane to gank repeatedly and get ahead. That being said it's a requirement for your teammates you're getting ahead to not be complete mongoloids.
AD fucking C
Jungler. By far.
As a S1 Jungle main. Jungle and mid have been the least impactful so far. Top and bot have been the most impactful because they can often get so far ahead of their lane counterparts which have devastating effects on the outcome of the games.
Midlane since the Jng nerfs.
