Found an Interesting Quote in the 7.4 Patch Notes
"Ultimately, we want a player’s impact to come from the decisions they make and the actions they take in-game. Masteries supplement that power, but over time the amount of power they bring has crept up. We like the gameplay that is created by impactful Keystone masteries, but we’re looking to trim some of the invisible power from masteries which only provide passive stats."
So that's why 18 patches later runes with overloaded stats were implemented with big dick damage like Coup de Grace (lowest tier rune btw) giving 7% more damage to low hp targets (40%) with an added affect of gaining 9 bonus AD or 15 AP on takedown compared to the old mastery Merciless giving 3% increased damage to low hp targets.
Or Celerity which could've just been 3% movement speed but wasn't fulfilling enough because fuck you lets have more damage (9.6% ad 16% ap adaptive based on bonus movement speed)
Or Absolute focus giving you 24 AD or 40 AP until an enemy clicks on you once because there couldn't have been different options that didn't have to do with damage.
Or Water-walking that could be a nice little rune that just gives 25 movement speed in river, oh no that would be incomplete without 18 AD/30 AP
Free stats not enough? Don't worry just punch them in the dick and set em on fire with extra ability damage through scorch (20-60 magic damage) and cheap shot (15-40 true damage)
Unique use of vision in the middle of the domination tree? Nah I'll just take damage and free stats instead with eyeball collection (30 AP 18 AD)
There's probably a few runes I missed but we all get it
The only real decision we have to make this season is in champ select.
