2 ideas to fix lethality
- If lethality cannot cut through more than 80% of the enemies total armor if they are under 50 total armor.
- Have it need to ramp up like
where you do not get all of the lethality on the very first hit. You only get a small portion each time you apply damage. That way champions like 
and 
can't just almost instantly kill you at level 6 with very little attacks being used (like just 1 auto and 2 abilities). They would have to apply new damage a few times to get the full lethality.
