Morde not only needs a baby sitter, but can also only be picked on red side now, wtf?
A pick that leaves a team w/ no ranged damage for team fights is likely to never become a strong meta pick. So for Morde to become a good option he will have to be paired w/ ranged AD in other lanes (Ez or Corki mid maybe, Vayne top if solo que can pull it off maybe), and unless you can guarantee picking a ranged AD for a solo lane (which are limited options) he's not any good, so if he becomes pick/ban status there is a chance that he has to be banned by blue side because they can't pick two at once (assuming it is strong enough to be worth picking first rotation). WTF riot, definitely balanced for one side to have to ban something consistently.
