Kassadin gets countered hard by ad assasins, preferably talon (silence, that's why).

Also, we all know that there are some serious balance issues on some champions you mentioned here (*cough* Kassadinnoskilllnoobchampopnerfpls *cough*) There is a counter to every champ (except Yorick, maybe) you just need to find the one you can play with. (Also you forgot to mention Akali here, she's in my opinion more annoying than any other mid champ.
