But now it becomes just another midgame strategy that you have to be on the look out against. It adds a bit of danger to the game and makes it more interesting in my opinion. The game does not degenerate into a contest of who can use it first, it requires a good sense of timing and misdirection to pull it off successfully. After all, a good fencer can score a lot of hits on you with his rapier and still get away while you are slowly swinging your broadsword. A last comment.
People complain that paralysis is too strong.
If you continually paralyze your opponent with one hand you are effectively losing the use of your paralyzing hand as well. It leaves both of you with only one hand actively casting useful spells. The main advantage to the paralyzer is that you can break it anytime you want to. Then all you need to do is make one of your gestures a W on turn 6. This would make FoD less popular, but if you can't protect FoD with FFF then its popularity will suffer anyway.
