Lethality Buffs Are Way Too High
I have made several posts showing the math regarding Lethality.
The changes done to Lethality currently on the PBE was to make it scale better.
I still run full Lethality runes and masteries. I sacrifice a weaker early game for a stronger mid to late game.
Pre-Lethality, with armor penetration marks and quints + masteries, you would get 22.3 armor penetration at level 1. At level 18, it would be 27.5 armor penetration.
Currently, with 33.5 Lethality from the same set up, you get 43.3% of that at level 1, or 14.51 armor penetration. At level 18, it would be 33.5 armor penetration.
With the changes on PBE, with 33.5 Lethality from the same set up, you get 62.2% of that at level 1, or 20.84 armor penetration. At level 18, it would be 33.5 armor penetration.
So if these changes go through, what was the point of introducing Lethality? We are going to go back to full penetration items from everyone, except now they all have more armor penetration. Duskblade is already core on my Garen, and with the changes to that item, I will be doing 75 + 48.5 x 2 = 172 True Damage on him from only one lethality item. You can get up to 83.5 Lethality, so you can do 242 True Damage now.
With these changes, I will abuse Lethality and Duskblade even more now, as can be seen here:
