"Toning down Brutalizer was WAY too much."
Wait... too much for what? I'm not understanding why Brutalizer is a problem. It has been in the game for years. Considering AD casters already took a 3 or 4 ArPen hit from runes (factoring in that ArPen % applies first now), a 5 ArPen nerf on Brutalizer would mean... 10 less ArPen early game on AD casters.
The trade-off is a Black Cleaver, which isn't really that strong anyway, at least for the role that AD casters are supposed to fill (killing carries). I don't want to kill tanks, I don't want to be weaker early game. That is why I play AD casters--I like to be strong early game, weak late game (more or less). Why not just remove The Black Cleaver altogether? Leave Brutalizer, Yuumuu's, ArPen, etc. alone. As it is now, you're simply stealth-nerfing AD casters early game and making them stronger late game, making them more like carries.
So, weaker early game, stronger late game. Where have I heard that before? They've been doing that **** to champs like Urgot, Garen, Pantheon and Renekton for a while now. They want to make all champs equal in all parts of the game, apparently. No diversity.
