my idea to see anivia

I love to see so mutch champ diversity in the lanes, but i would love to see anivia in the mid lane and I have, what I think are, good ideas to make this happen. first i think if they made it so that her ult wasnt stoped by everthing and insted of being cancled by stuns, silences, etc. she cant cast it or cancle it. My second idea for her, and the one i realy want to see, is that they make it so that her wall is casted the same way rumble ult and victor e work. where you click drag click and that is where the skill goes. this change would ope a lot of opertunety for zoning and out plays in places both in lane and jng with out having to think 7 steps ahead so newer players could play the champ and still do well while still rewarding the skill players by being about to block of a choke forcing the time to fight and not have to be in realy risky stop to do so.

ps this is my first post so please dont be to harsh if i did something wrong and please give me your ideas i would love to see what you guys have to say on my idea and see if it is a good idea or just something that cant happen and why.
