Junglers in competitive are steadily 3-4 levels below their solo laners.
And supports 4-5 levels below, because they're pretty much forced to give up their share of exp to their ADCs.
The result is that, in the average proplay midgame, MID and TOP are level 13, ADC is level 12, Jungler is level 9 and support is level 8.
Given those grim signals, you'd expect every alarm at Riot HQ to be ringing for a quick, decisive solution.... but apparently not only at Riot they're okay with that, they state it's intentional.
So, the optimal support gameplay has regressed to agency levels of the times where they were mere ward bots in S3, and optimal jungle gameplay has you running on a timebomb in a desperate attempt to spam ganks in the early hoping to get your carries fed before this strategy turns you into a cannon minion with utility.
That has become peak league of legends.
Shockingly, that's considered balanced, because questionable datasheets from Riot say that all lanes now have equal agency in winning or losing the game. No one is actually enjoying it, the game, but everyone has equal impact over it
