Who (in your opinion) is the most dominant mid during laning phase?

Things to consider would be:

Range Damage Ease in countering/counterplay

and anything else that you can consider.

In my opinion, I believe that Syndra is an extremely dominant mid laner who is very difficult to counter when she is played to her full potential. This is probably because she is extremely long ranged, has extreme single target damage, can cast all of her spells while moving (this is actually super important), has short cooldown on her Q, and she can peel for herself with her E.

Anyone else with a different opinion?
