Pushing Mid
I'm a fairly new player to league and I was wondering when is it right to push mid. I play a lot of anivia and ori. When I play anivia I generally freeze until my mana pool is built up (tear+catalyst/roa). Once I have these items I shove hard to make my opponent have to farm under tower in hopes that they'll miss more cs and to allow me to roam. With ori I only really shove when i plan on backing. Should I be hard shoving once I hit a power spike or generally just freeze unless going for an objective(drag) or backing.
Thanks for any responses!
