they took his damage to towers down and im pretty sure they did it overall. he use to hit 22 on towers at low levels with no damage items on and now its 18.
You sure Yasou was hit?
Tower damage is really odd and based on a lot of different factors.
There armor changes based on nearby minions, they start with a hefty amount of damage reduction, and they actually grow in strength and level up over time - there HP is even based on the number of champions in game.
AP also influences damage vs. towers, they take 100% of your base AD plus the higher of 100% of your bonus AD or 40% of your total AP in AA damage.
One thing is pretty consistent with towers: they have a ton of armor and damage reduction. a minor 4 damage difference vs. towers will generally mean a substantially larger difference vs. other champions, minions, and monsters if it's on the champion-specific side. Which makes it extreemly unlikely Yasou's damage was hit.
Also - 1 level difference is a solid 3.5 AD, or with 100 armor 2 levels will increase vs. tower damage by 3.5. Being 2 levels off will give you the damage difference you listed, and you never specified a specific level, just "low levels". vs. tower-damage increases with every level.
Not to mention Runes and Masteries give very real item stats at level 1, and together can account for some pretty noticeable changes in a champion's starting stats. As I mentioned previously tower damage is influenced by your AP, which makes it even easier to shift vs.-tower damage between games with different mastery set ups.
so - you sure Yasou was hit?
