Personal opinion: Damage erases skill expression

Here's a scenario: You're playing Lucian, and your support, Lulu, are bot lane, farming under your turret. Enemy Thresh throws a hook, which you dodge perfectly. Ashe oversteps a bit, Lulu polymorphs and slows her, Thresh throws a lantern but it's too late, she's dead. Thresh backs off and hangs around for exp, while you hard shove the lane until you notice a TP going in the lane bush closest to your turret. That's a fed Garen teleporting into your lane. No problem. You and Lulu back up, and decide to b under turret. Top is dead, mid and jg are hard pushing. Suddenly, you see the dumbass Garen running at you while tanking turret, which barely does anything to him. His Q is up, but that's okay. Lulu polymorphs him, and throws a Q at him when- OH SHIT RENGAR IS ULTING. Lulu ults and shields you right as Rengar is jumping, and you heal and flash, but the 6/0 Rengar has already deleted your hp bar in 0.9s, while Garen runs at Lulu, eviscerating her with a Q+E+R.

See, with the current state of damage, most people die in the blink of the eye as soon as they make mistakes. I believe this is toxic for the following reasons:

1. Low-elo players such as myself have very little room to breathe. We're all going to make mistakes at some point, but we can't learn on how to recover from those mistakes if the punishment is getting oneshotted by a Yasuo.

2. Skill is only valid for the first ten minutes. After that, it's usually a one-sided stompfest where the team with the most kills just shits on you with point click damage. You might have vision everywhere, and you might've dodged most of the cc, but nothing will save you from a Talon Q if just one person has fed him.

3. Games can literally be thrown by one feeder. All you need is a shitty midlaner who feeds Zed three kills. Zed then constantly roams bot, forcing you to either hug turret or to die, or he walks around in your jungle, picking you off in a 1v1, or going top and just turret diving you.

4. Point and click damage. You have no way to avoid this, unless you're playing someone like Fiora, or use Zhonya (Except the ability will be back up in 10s anyways). This is especially true for assassins such as Rengar, who, if you let him get kills, have fun getting one shotted.

5. It's difficult to come back from. Farming past your turret, or even at your turret, is nigh impossible when the enemy Yasuo can just dive you with the Vi camping you. Vi ults, Yasuo ults, you're dead, they run away from your turret with half health. It's also a catch 22, because if you farm under your turret, it's generally because the enemy wave is also under your turret, meaning they can divert turret attention while the enemy turret dives you, but if you farm normally at the middle of a lane, enemy can easily close the gap and either zone you away from cs, or kill you.

I'm okay with getting killed by assassins really quickly, I'm just not okay when they shred you with heal+shield up, with an ability you have no way to avoid. Anyways, just my two cents.
