Lethality and Armor Pen needs to do it's job

People are complaining about the Tank Meta and have been, and with the mage changes, and the changes to the jungle and the adc nerfs, people are obviously gonna look at the only thing left. This is something they need to do

Make armor penetration and lethality do it's job

I'm not sure how they would do this, but hear me out. Tanks build armor versus AD Champions. the flaw with this is that armor pen and lethality makes you deal more damage to squishies because it's a flat rate. IMO they should replace all lethality items to a flat % total armor pen, balanced of course. example:

let's just use this as an example, too lazy to crack up the actual specific numbers

if you have 50 lethality, and it ignores 50 armor, an adc with 70 armor is only going to have 20. that makes you do WAY more dmg to that player. if you have 50 lethality, and it ignores 50 armor, a tank with 300 armor is going to have 250. that's still a LOT of armor.

The job of armor penetration is to penetrate armor. that's what the name literally means. here's my proposal"

instead of having 50 lethality, how about have 30% armor penetration?

if you have 30% armor penetration, an adc with 70 armor will only go down to around 46-47 armor. You'll do a little bit more but not much. if you have 30% armor penetration, a tank with 300 armor will have 200, which is significantly more.

Yes, tanks are a little dumb right now, and they get broken down pretty quickly by adc's with crit currently. They're fixing that. But it makes no sense to have duskblade, youmuu's, and edge of night and 2 shot a marksmen, and have very little damage difference versus a tank that's actually building armor. The point of ARMOR PENETRATION is to PENETRATE ARMOR.
