His scaling is too good for a champion of his kit. You can't give someone 140% Total AD ratio on a Q, a 160% total AD W, knowing they are going to build trinity force and black cleaver, and on top of that give him free 30% armor penetration on his E, plus a hard CC, PLUS a soft cc on his crippling strike. His kit is overloaded for what he's suppose to do and something needs to be done about it.... Without touching items that other champions rely so heavily on. Darius was never a champion build from the ground up meant to use trinity force and have more true damage on top of his ultimate.
