Lethality has been a nightmare to balance and is extremely counter intuitive.
They should honestly just get rid of the two new lethality items and replace them with two others, and revert everything back to flat armor pen. Make adjustments to assassins as necessary.
IDK exactly what you did but having people build all 4 armor pen items and there being zero way to not get melted by them was a terrible idea.
Protip: Get good.
The main issue I see with lethality is that the stat itself doesn't scale with these assasins add all. I would like to see something like increase flat AD values or % damage on their abilities for having lethality. Take Talon passive for example:
INNATE: Talon's abilities wound enemy champions and epic monsters every time they deal damage, lasting 6 seconds and stacking up to 3 times.
Talon's basic attacks against enemies with 3 wounds consumes them, causing them to bleed for 60 - 160 (based on level) (+ 200% bonus AD) physical damage over 2 seconds.
What if they do something like this:
INNATE: Talon's abilities wound enemy champions and epic monsters every time they deal damage, lasting 6 seconds and stacking up to 3 times.
Talon's basic attacks against enemies with 3 wounds consumes them, causing them to bleed for 60 - 160 (based on level) (+ 100% bonus AD) physical damage + ("0.5% every 1 Static Lethality" of their maximum health as physical damage) over 2 seconds.
