This is kind of dumb.
If I'm ANY of the tanks you listed vs any of the other champs listed, there's a reason I can win that early 1v1.
I'm on Mao, and I hit you with a Q for a decent amount of base damage and now can proc aftershock. Your early damage is now pretty abysmal so you've got to run, but you're now slowed. Any damage you did to me, I can heal back up with my one passive, and now I get my aftershock proc on you and you get a pretty decent chunk of damage done for lvl 1. Even if it's a Fiora vital proc, my passive will give me a decent amount of sustain to deal with it.
I'm on Malph, and I engage from range with a Q + comet. Not a whole lot you can do about it, even if you close the distance to engage because I've got an armor passive. Now I can just chase you till my Q is off cooldown and hit you with another one.
Ornn? Start W, use it when they engage. Any damage they do is dealt to your shield, and you get two decent instances of %hp damage on top of your aftershock damage.
Why is this alright? Because that level one fight is at a point where no one has purchased anything meaningful in terms of offense or defense, and they rely entirely on their Doran's item + runes for combat stats. And if you play into a tank's decent level 1 win condition then yeah, you played it fuckin terribly.
Maybe DON'T go in for that losing engage, and go in once you maybe have a second ability? Like on Fiora, once you've got both your dash and your riposte. Or for Renekton, both your stun and your heal. Or Irelia, your dash and your stun/slow.
Identify your win conditions and play to them. Don't just rush in like an ape and them complain when it doesn't work.
