its not just top laners. its also marksmen.
riot doesnt know what theyre doing with their own game anymore. they had this system of clear cut power curves of champions that are strong early and mid game, then fall off towards late. other champions had a weak early game and scaled into a strong late, and others were just reliable through the entire game.
then they went on this crusade to cut game times by 10 to 15 minutes and lategame basically doesnt exist anymore, so all these lategame champions basically got removed from the game. crit marksmen, veigar, nasus, some skirmishers like jax and other lategame champions that relied on stalling out games to carry later because they were weaker early.
then riot buffed all these lategame champions early games really hard (verigar got buffs to his w, nasus stacks much faster, marksmen hit their power spikes off 2 items instead of 3 or 4) and fucked up the entire balance of power curves in this game.
there are champions now that are decent early game and scale into such a mid and lategame that you question the balance teams sanity. at the same time you have champions that are straight up shit early to lategame. its complete chaos.
look at
power curve. 50% winrate during the early stages and then just drastically increases over time.
used to be strong early and fell of late. now hes just weak early, barely exists midgame and at later stages falls off like a rock.
crit marksmen power spike early again and bot lane dominates the game again, robbing top lane of their game impact. most of the time bot decides games now.
even after the change to turrets and the additions of plating, they basically still made sure that games dont last past 25 to 30 minutes anymore. because whats happening is pretty much that lane phase gets stalled out to 14 minutes (it used to last 15 to 20 minutes naturally in early seasons), then because of the extra gold from the plates, they want the game to suddenly snowball extremely hard and end as soon as possible after.
