Not enough variance in builds
I do hate how Riot have begun FORCING champions to play certain roles and if they don't, they suck. For example
, the new nature of her W makes it so you HAVE to be in lane with somebody else, before her rework you could easily heal yourself with it. Riot have got to stop doing this, one of the big things I liked about League was the diversity of builds and roles for different champions.
Why is it that Graves can go ADC/Jungle/Top and GET AWAY WITH IT while Soraka was destroyed just for going mid. Riot please stop destroying your own game to compete with other MMO's like SMITE and Heroes of the Storm. (I play Aphrodite in SMITE and she is a healer, like Soraka but she can heal herself and a target she kisses, making her ideal for solo lane play despite being mainly a support)
