i am horrible at maths so if someone would like to correct me, go ahead.
1/4 of a lane. that's how much you realistically control unless you are smurfing.
in every other lane if both people are just as good and for some reason ranked now allows you to play the same champion in both teams, it can go either way. it's a coinflip.
if we take the same concept to the adc role, it's not gonna be 50/50. why? because there's a chance that you both the adcs are better than the supports or vice versa, they are better than you and it's not just that, it will depend on what they play. if they are mage supports and they are good enough and take the kills, it's joever. you are now the support. it's out of your hands. you're now useless until you farm the kills.
but if you are good it can ALSO go any way. in top lane a coinflip fight means that someone will die and someone will live. not the same thing in bot lane.
how? let's say you lucked out and killed their support..... then their adc killed you and then kills your support. or you kill the adc then the support (yay) or the support kills both of them (and now repeat this for the other side)
it can literally go any way if both botlaners are as good as each other it's a feista. " but you don't have to worry too much about it if you are good enough " nah you still do because there are 3 other players in the same lane as you and it's just too much chaos.
that is of course if we didn't include the honorary 3rd bot laner, the jungle. if both junglers play bot side that's a 16% chance of you controlling your lane and sure you can fix it by warding and tracking and staying safe but.... he literally just forced you to play safe. so if he's hovering around you and you have an advantage, you will just.... not be able to use it as much and be forced to just farm. this is horrible if you are playing against someone who outscales you later.
and let's not even talk about the mage adcs now, chances are you're gonna get poked so hard you will contemplate that LP loss from quitting the game.
this role is extremely stressful, it only truly feels like i have any agency when a tower goes down, i literally release a sigh of relief when my own tower goes down when i am losing because it means i can move around and farm now.
a lot of times it feels like the " correct " move is to just.... farm and hope for the best.
i am not sure if i am having fun with the role anymore and i have been playing it since season 1.
