Okay so there's a commercial for w101 where boy and girl are fighting Malistaire and he attacks the boy but the boy has a shield. After that happens, the girl slides out her cards and taps one to cast on Malistaire. I think that if you don't have a wand in the game you should cast your spells that way. The arm-waving thing is getting old. And your cards aren't shown in a duel otherwise, which kills the feeling of you actually using them.
I think this is actually a very good idea. I wish the whole game was something more like the commercial. The graphics were great in that ad, and although KI probably won't improve that, some of the movements and zooming in and out was nice.
