I think Nunu needs a buff
I'm only level 13, so I've never faced a good Nunu, but it seems like Nunu has the lowest winrate, pickrate and banrate, and one of the lowest average KDA's. Is he like an insanely high skill champion or something? Because he seems to be doing way too bad, even for a champion with a high skill floor. I think he needs a buff, but I have no idea what he could be given. Thoughts?
