Midalee is VERY risky. You either get something that can let you freefarm and reach your late game safely or you get a lane bully/hard pusher that makes your life hell. All midalee has is basically her poke, she brings almost no utility except for her aspd buff (traps are a very gimmicky "utility"). Not saying she's bad, she works exceptionally well in the right team, but you can't just throw her into any team and expect her to be godlike.
Since you are too much of a coward to say it out right, I will do that for you: Nidalee mid is a complete garbage. Reasons: shitty ganks, shitty late game, no CC, low kill potential in lane, heavy mana reliance.
Whoever plays Nidalee mid sends his team a clear message: I got a down syndrome, please carry me.
