Wasn't lethality created so that it couldn't be abused by ADC's......? What happened... T_T

It was so refreshing to see ADC's buying crit items again...

That was not the purpose of lethality.
Lethality was intended to prevent people from snowballing too hard in the flat pen arms race (e.g. players always having more arm pen than the opponent had base armour due to level differences), but lethalitys pen scaling off the targets level limits that somewhat.
The actual tuning of lethality is still a bit up and down, but I'm pretty sure riot is perfectly fine with adcs building lethality, so long as it has trade offs with crit builds (e.g. crit should be better late, especially versus armoured opponents).
Lethality offers a much earlier power spike than crit. With games snowballing so hard a lot of ADC mains feel like they have to sacrifice their late game power to at least be relevant in the mid game. Whenever I play ADC and I go crit I feel useless for the first 30 minutes of the game. With lethality I can come online and actually deal decent damage in the mid game.
lethality was created to tun down armor pen in early game
not because of adc
Was lethality created so it couldn't be abused by ADCs?
No.
It was a straight up nerf to flat armor pen across the board. It didn't get nerfed harder for any class in particular.
Outliers that synergize well with the stat. Can´t be helped. Would be strange for Riot to nerf those champs for 1 patch because they wanted Lethality gallore in Blood Moon. Things will be back to normal soon.
The problem is crit. Crit is not consistent, and is expensive. It also doesn't start doing a lot of damage until after 3-4 items. People want to win games consistently. Armor pen gives you a consistent stat that becomes more powerful as time goes on, allowing you to in some cases do nothing but build lethality and AD, or Lethality and Crit, since the crit is just bonus damage to what your lethality already gives you
I just played a game as lethality MF. MUCH more reliable damage than crit based damage.
I'm pretty sure almost all ADC who don't need much attack speed benefit much more from building lethality.
Yeah, but wasn't armor created so that tanks wouldn't die in < 2 seconds to physical damage? what happened?
