No you haven't... until you hit level 30 and gotten to go a few rounds with her, you have not played her... at all.
That wall has scored me many a kill, and has also allowed me to land Flash Frost much easier (or I can use my ult and pop Frostbite for extra damage), its one of the best skills in the game for screwing with the enemy team (nothing is worse for a team when their carry is now on the enemy team side of an icewall they can't get through).
Anivia is one of the stronger champs in the game, to say the least, if you can build her correctly she can easily be the deciding factor in fights.
Heck, I barely even try on her any more on her and I still get a decent score (usually happens when the team fights break out and we need to push)... she's great at pushing lanes with the amount of AoEs she puts out, too... why would you want to change an already viable (and very powerful) character?
