Ryze might need nerfs after AP item changes
Riot essentially compressed his 3 item powerspike (Morello Seraph's Mask) into just Seraph's and Mask. It's no surprise that his winrate went up 5% this patch

and as we all know, when Ryze is over 45% winrate he's probably the best midlaner in the game. He's at almost 49% for today.
