difference between bot lane and top lane.
bot you have 3 champions viable for a couple weeks who arent marksmen. "cancer, must nerf, cant play my adc, riot garrbage, revert crit changes". bot lane gets reverted in less than a month before even giving champion diversity a chance, and a couple patches to make by balancing the champions out. not even talking abbout the crit item revert, but they immediately buffed marksmen, and nerfed every non marksman who went bot lane until it was just back to a marksman only lane long before i.e. got reverted.
top lane: "wow so unique, must preserve, ranged always countered melee top, just normal, tank viktor/karma so fun, top lane vayne no problem youre just salty bruiser main."
top lane is literally the garbage bin of the game. every champion they dont know what to do with theyre just like "let him play top lane". so they dont care either when actual dumb shit like aftershock mages and glacial augment ranged champions ruin the experience for half the champion pool up there.
this is why league is bleeding players and matchmaking is shit this season. they dont have a consistent design and balance philosophy. some champions are allowed to be more relevant, and stronger than others just because. it doesnt have anything to do with the algorithm. there are just not enough people playing anymore to make balanced teams. go to google trends and check "league of legends interest over time" kek.
i mean part of it has to do with the new player experience being so utterly garbage, that barely any new players can stand to stay long enough to get an account to 30, but if you shit on your existing player base with terrible gameplay and champion balance on top of it, then youre gonna lose players. go figures.
