@Ironstylus: While the others are retooling Diana, how about your thoughts on another knightly lady?
Leona's still my favorite Solari tank, and nothing's gonna change that. But League could still use more armor-clad ladies who can take a huge hit and still keep coming. But on that note, I think that there also needs to be one of a... darker path.
You've probably seen me toting this one around before, but I just recently gave her a significant retooling, and she could use a Rioter's feedback.
Nephree, the Dark Crusader

General Concept
Nephree's a physical-damage armor-tank who is built around punishing enemies who attack her via counterattacks, while also forcing them to attack her via taunts. She wields an ancient cursed sword in Demacia's name, but is constantly beset by the fear that the curse may turn her from a righteous path and make her as wicked as those she fights.
