Darius and fiora

let me run some stats. in total Darius has a 46% win rate,92% ban rate and a 4.76 percent pick rate. [(http://champion.gg/champion/Darius/Top)] and fiora has a 50% win rate a 75% ban rate and a 6% play rate [(http://champion.gg/champion/fiora)] Now what should we do with them and why. Im leaning towards removing Darius because hes unhealthy for the game and reworking flora again like making her ap or making her into a full on jungler
