How do you capture a wizard?

[Emperor Tippy]

I doubt they are all idiots. Its more likely they simply don't have the time to think of everything, let alone playtest it. I don't know about WoTC, but I know that at Games Workshop most books have less than a two month development cycle from the moment they are assigned the project until the manuscript is delivered to the printers. That isn't a lot of time for careful thought or testing the implications of everything.

You don't need careful or thorough testing, grab someone from the TO boards or the like and have them read through the stuff once before it goes to print. That's all it would take to stop 95% of the broken stuff from ever seeing the light of day.
