Do Tower Gold and Ranked Changes Make Ranked Too Stompy?

This is a serious query more than a complaint, but I have noticed a significant difference in how stompy games have been this season compared with previous ones, and this appears to be the case no matter what ELO you're in. I'm low Gold ELO and it happens to me all the time, but I also watch Diamond - Challenger streamers and it appears to be happening to them at increased rates as well.

I think the tower plates are the biggest problem here for all ELOs.

Riot claimed towers would be tougher to take, but provide some extra gold. However: towers are still paper. Realistically speaking, they are a bit tougher than they were last season. But to my point: there was a TSM game recently where they took literally every tower plate available, which means they got every outer tower before 14 minutes. I don't think that should be possible (or at very least, it should be extremely unlikely) if Riot's stated purpose was to make towers more difficult to take in lieu of some extra gold. I even remember reading about how taking every plate was supposed to be extremely uncommon, but I see it happen almost every single game.

What ends up happening instead, in my personal and observed experiences, is that winning lanes snowball so hard that games become unwinnable, especially at the lower ELOs where coordination is more difficult to achieve. If a winning lane takes a tower before 14 minutes in my ELO, that means the lane is likely: 20-40 farm ahead, 2-5 kills up, and stacked with an extra ([160 x 5] + 200) = 1k GOLD just for taking first turret before 14 minutes.

What this means is that another lane on your team needs to be smashing at a rate roughly equal to the smashed lane in order to even have a chance to come back, assuming your team hasn't already tilted off the face of the Earth (very rare scenario). And even then it becomes a matter of who translates that victory to the rest of the team first, which is a crapshoot in silver/gold ELO particularly, where people aren't always sure what they should be doing when they're ahead or how to translate their lead to the rest of the team. If there is no one to challenge the fed enemy, then that 1k bounty on their head might as well not be there, because they are so far ahead that they are virtually unkillable.

To focus again particularly on lower ELO, I think the other large contributing factor is the new ranked system in which each role is ranked differently. I won't pretend to understand the intricacies of how matchmaking works in these instances, but what appears to happen is that I get put on a team of people around the ELO of the role I'm playing, and we get pitted against players around the ELO of my highest ELO role. I was literally in a game where I had a Bronze 1 and an unranked player against a team where the lowest ELO was Silver 2. The game was over before I even left laning phase.

I think this all contributes to an even more common "I give up" mentality I've noticed this season. I played over 20 ranked games this past weekend, which is significantly more than I usually play, and in literally EVERY one of those games I had someone on my team losing lane by minute 5-10 and express to the team that "it's gg" or "this is over" or "I give up". I don't mind being a positive force for my team when they're losing hope, but when this sort of thing is happening literally every game for 20+ games, it's exhausting (especially when you're a jungler and people are blaming you for not helping when you're across the map taking your 3rd camp of the game).

TL;DR: Turret Plating gold makes winning lanes so strong that the bounty system doesn't even matter, and the new ranked matchmaking seems even more imbalanced than it was previously; the result of these issues is excessively stompy ranked games this season that is fostering a mentality of surrender and hopelessness at the first sign of a game's decline.

Those are my observations. Does anyone else notice something similar? Notice anything different?
