Karthus the Forgotten Champion
Almost every single mid laner I've seen has had some kind of change whether it be a buff or nerf. However I've never even seen any changes done to Karthus ever and he is FAR from perfect. Is this because Riot feels like he is balanced? I mained Karthus s2,s3 and s4 and managed to get d2 during s4. He feels like absolute trash right now. Every single mid lane champion dominates him, hard. The ahri buff literally made me flip out because EVERYTHING she does counters Karthus. Im so sick and tired of playing against zed, LB, ahri etc. Every matchup is a goddam nightmare for karthus. Not only that, but Karthus has SEVERE mana problems in lane. You cant even afford to go offensive unless you're willing to oom yourself and losing an entire wave. Everybody who comments is going to state "oh but his late game is insane" no its not. Everybody will have a banshees and you will get popped so fast in a team fight its insane. Sometimes you will get popped so fast that you cant even zhonyas.
What im trying to get at is that every mid lane champion excels in atleast one aspect. Karthus excels in literally nothing. He feels ridiculously weak when playing against semi-competent people. He just gets styled on in every regard and there is really no reason to pick him.
say hi, just to name a few. Mages are feeling somewhat neglected, well except Ahri. Assassins have been getting a lot of attention though.
