Mead, Middle Line, Central Corridor - Lonely Monk Alley
The center line is the most memetic but also the most influential line in the game. It is home to solo-kerries with explosive damage, assassins, skirmishing control mages, and other heroes strong in one-on-one skirmishes and massed team fights.
The absolute requirement for every Meader is to have a personal micro skill and the ability to survive on the shortest and most open line. This requires, at a minimum, learning how to look at the mini-map and being a bit of Vanga, predicting the appearance of opponents on one side or the other.
The Meader needs to farm a lot, stand in a line as uncomfortable as possible for the opponent, and harass the enemy for every attempt to approach a minion. And only thrill if you can make it happen - my personal observation is that players in the center should have mental resistance to what's going on in the chat, as well as know the location of the mute button better than anyone else.

Bottleliner, shooter, ADC - mechanically gifted fighter
Positioning, positioning and positioning again. Of course, like every cor character in the game, the shooter needs to farm, hit with skills, and try to punish his opponent for mistakes. However, the main thing for the core is the ability to get up (and keep moving, not being a turret!) at the right point on the map to right-click in a team fight with impunity.
This requires understanding how a team fight is constructed in general and how damage should be dealt with at a distance. This can easily be understood if you talk to professionals from https://anyelo.net/ and see how skillfully they handle heroes.
It works in classic arrow melee (beginners are better at choosing heroes that do most of their damage with auto-attacks) and in the case of non-standard bot lane heroes. Yes, if you got your hands on Ziggs on the bottom line or Yasuo, who decided to escape to the bot, the rules of the game will change slightly, but the key task - to destroy your opponent in a fight as quickly as possible - will remain forever. One catch: in any team fight, you are the most vulnerable opponent.
Support, support, "wardilka" - you are a steward, a reaper, and a horn player.
Riot Games has been working for years to ensure that their Sappors can be full-fledged combat units rather than bots for placing wards. The developers succeeded: now the support champions get enough gold to collect the same number of items as other heroes on the map.
His tasks are different depending on his peak (we'll talk about that below), but in the end, they all boil down to controlling the map and the enemy units, protecting the kerries, and keeping the teammates informed about the enemy's location and their kuldowns.
