*cough* First of all I'd like to mention that I was the first one that mentioned the spellplague to Matt. (I was asking when it was going into affect, assuming he knew)
Second: I forgot to mention that the only other thing I disaprove of, is having to use your hands. Why not use like, twice as much oncentration to do it with your mind alone? (so if someone is just standing there talking about killing you, you can -not- be paying attention, and be working on a spell that'll either throw them into a hazerdous object, or imobolise/kill them alltogether)
I stated an example like, quite a while ago. I think it was in the last spellplague thread.
