The game...never gets to late anymore

Every game I have been playing or watched seems to end between 15-30 minutes. It often seems like the game is over at 10 minutes. I like getting to the late game and specifically like late game scaling champions. However, it seems really hard to do that now. I know a lot of changes have been implemented (and I'm familiar with the details of 5.22) but I can't quite place why this huge feel in the pace of game has taken hold. Towers being weak is nothing new. I've gone to late game after my team had lost all three tier 1 lane towers in early only to be behind by tower gold + a bit more only to come back and win the game with our scaling. One lane losing (even to a Yasuo) was never an impossible task even if they snowballed because some well placed CC could always keep them focused down. I haven't really seen people taking huge advantage of the Herald. The items seem to all be more expensive and have lower stats (except tank stats). There is an abundance of crit but games lost are just as often based off a snowballing AP as an AD. Now...it is almost an impossible task to get to late. It's like it became super easy for the enemy (or my team) to siege in the early game and have some sort of huge stats advantage pre-20 minutes.

Try as I might I just can't wrap my head around why. What exactly is causing such huge upturns in power in the early phases of the game and why does early mid game seem so insurmountable when behind? Anyone have some insights? I would really like some details as to what is going on beyond "because 5.22 update is crap". Perhaps if I can figure out exactly what is causing this I might be able to change my play style to help combat it.
