Add Lethality or Armor Pen Boots
If you don't feel like reading my explanations, you can go all the way to the conclusion where I sum it up in the least amount of words as I can.
How is it okay to have magic penetration boots but not lethality or armor pen boots? So you're saying it's okay to not have MR runes no Armor runes, but you can still have magic pen boots? When players build Merc Treads to lessen the magic damage and cc, you can build sorcerer's shoes and problem solved. Mages and other magic dmg builds can still deal a considerable amount of damage even when tanks and other champions build MR items.
Let's go over to the auto heavy AD champs. You could fight and lose for whatever reason in the top lane and still have a fighting chance right? WRONG. The enemy builds Ninja Tabi's and instantly you are countered and behind two levels. You don't even need to be losing. You could be winning lane and they slap it on and at the moment they buy Tabi's, you become weak. You can no longer fight, trade, or poke as a melee champ because Tabi's reduces your basic attacks by 12 percent. TWELVE PERCENT!!! AND reduces the damage from basic attack modifiers. What boots do you build to counter that? Berserker's? Conqueror still loses to Tabi's because conqueror's only lasts for 3 seconds. Assuming you're fighting against a tank that builds Attack slowing armor or has cc, another AD counter, you're not going to be able to do any real damage before the rune runs out. Building armor pen items on auto attack champions takes gold and it takes away from attack speed making it more difficult to win fights or deal an appropriate amount of damage. At the same time, there are more champions on the enemy team that make building armor pen useless because they don't have armor and your turret siege becomes slow. Conqueror's is only a rune you take when you're going up against another bruiser where both of you are constantly fighting each other and constantly trading.
Staying on topic with auto heavy AD champs. ADCs. Let's say a good portion, 2 -3, enemies are tanks with a fair amount of cc. When those tanks build Tabi's for whatever reason, your damage automatically goes down. If they decide to get on top of you, unless your team is protecting you, you will die before you can even damage half of the tank's health and that goes for the rest of them. You end up taking 20 shots each to get the kill and that is not effective or fair. Building armor pen takes away from other items that will allow your ADC to deal more damage to other champions and objectives. So usually, ADCs only build one armor pen item and the rest are crit/AS. Tabi's helped ADCs not get one-shotted by assassins, but at the same time, it helped every other lane win fights that should not have. This to me is stupid because assassins are supposed to one-shot targets. Not be stopped by Tabi's. Exhaust and sustain supports are supposed to help stop assassins.
In Conclusion, if you don't want to read all this, I believe there should be Armor pen or lethality boots to counter Ninja Tabi's because Ninja Tabi's counters every Auto heavy AD champ. Sorcerer's shoes are a counter to Merc Treads and other MR items, but there is no counter for Tabi's or other other Attack Speed slowing Armor items.
PS: Before you say armor pen items counter tabi's, magic pen items counter merc treads. So, why are there magic pen boots but not armor pen boots? Leaving magic pen boots out of it, tabi's is still overpowered. Even before they buffed the auto reduction. The item itself, is stupid. There are more armor items than MR items so MR boots are fine. Either remove Tabi's or give us boots that counter it.
does a % of true damage ... i think we dont really need more armor pen
