Addressing everything
Pulled off of my "Shut up ADC mains, you're just mad bot lane has diversity now" Ft. Caitlyn Part Two discussion:
Here are some changes that have been repeated over and over in this echo chamber of the boards:
"Nerf lethality"
"Nerf Lethality ITEMS"
"Remove lethality"
"Don't introduce spear of Shojin or Atma thingy" (Thank god they didn't)
"Buff towers"
"Buff objectives"
"Don't introduce the Rift Scuttler changes"
"Buff Armor"
(I added a few less related changes in order to explain that not EVERY idea the boards comes up with is bad.)
Out of these opinions, I find a few of them to be good suggestions.
Nerfing lethality items is a good start. The damage doesn't actually come from lethality and flat armor pen itself, but the add-ons that the items have. Youmuu's ghostblade has a 6 second movement speed buff available in less than a minute after using it. Draktharr gives you vision management AND a hefty autoattack burst. Edge of night gives a spell shield that requires 1 second of charging. Despite Edge of night's already decent ability, it's not being used. Why? Because abilities like an extra 30-200 damage on hit that can be augmented, combined with 55 AD and 18 lethality, combined with abuse of Stormrazor, combined with so many other factors, all for 2900 gold, mean that you can get a lot of value, and more potential value, through buying a first item for AD Assassins. Of course, Stormrazor was intended for ADCs, which is a good joke, because only Jhin and MF can use it well. Most other ADCs use it to prevent themselves from dying, and keep themselves at a miniscule level of relevance in skirmishes earlier in the game, as a first item.
Next, buffing towers would be a good way to increase game length. I'm tired of 15 minute matches where one team has a 10 kill lead, even if that team is my own.
"But wait wait! So many people complain that you can't solo carry, but others complain that you can't win as a team once a lane is fed. Why is that?"
I think I've found the reason.
The people that complain about not being able to solo carry don't roam as much, or aren't good at snowballing. Taking that advantage, and spreading it to other lanes that are stagnant can have a domino effect that end the game. If you're a Zed, but every other lane didn't do too well, and you didn't do anything but stay mid, sure you might get first tower, but you can't take down a tank, a support, an ADC, AND your angry midlane opponent. Unless you outplay them, you're not winning that shit.
However, if a player feeds their opponent, and they roam a lot and snowball every other lane, it feels like once one lane feeds, the other lanes get fed too. That's a result of good snowballing, and that's where the problem with this "snowbally meta" comes from.
As a result, buffing towers could at least give time to stagnate snowballing a little bit, and reduce its effectiveness when properly executed. It's like Riven. Once someone's good at her, it becomes very effective. If it's your first time playing Riven in anything above Bronze V, you're not gonna do it well.
Buffing towers' damage AND health/armor/mr would enable turrets to be more effective at what they do. However, I find the farming patterns in minions to already be commonly adjusted to, so if damage is buffed, minions might have to have a passive that reduces the damage turrets deal to minions by x% or something.
That's it for now, and then if the problem still exists, then they can adjust the scaling of the nerfs/buffs.
