The R is lacking...

First thing's first, I'm a Karthus main, and I've been begging for months for a karthus skin that would actually be worth my time. But this is not the goal of the discussion dw. It's been long on my mind (and the minds of other Karthus mains) that karthus is in need of something new. Besides the fact that the only major thing you have done to him was reworking his character model, Karthus remains one of the oldest and unchanged champions in the game. The patch buffs have been helpful, but otherwise otherwise karthus has not changed one bit. I'm not sure if I'm asking for a rework since you probably have more important things to focus on atm. However, the gameplay for karthus has not changed since he first came out. Int here int there...press r get kills....spam Q...then int some more. I do not agree with the "low skill" or "braindead" champion as people often call him. His kit is just VERY BASIC. He's an amazing powerhouse and extremely effective champion, once you get past all the r or inting memes. I ask that you please consider adding more to him, but at the same time keeping the major aspects that make Karthus Karthus. Very few people play him because his simple kit and usage prevents people from seeing his true POWER! Thank you so much for your time if you read all this. (also, pls improve his skins if you have time to spare :D )
