Champions i dont like to play against:
-Blitzcrank. He will miss his hooks 9/10 times, but when he finally lands one its game breaking.
-Urgot. He just seems too tanky for how much damage he does. Most of his damage is done from insane range which makes it difficult to trade with him.
-Morgana, imo is the strongest champion in the game. I started playing LoL right after Lee Sin came out and i have always considered Morgana the strongest champion in the game. However, i havent played with or against her since the CD on black shield was increased.
-Diana seems a bit too tanky and mobile for how much damage she does. Her AAs still seem to do a lot of dmg for an AP champ. Diana just has too much. High mobility, the AoE CC, good burst, very tanky...think of her passive...then all of her individual abilities... now compare her to some other champions.
