I like sword and shield for the ability to cash a random shield. Think about it, most bosses have a minion. Most of the time they're different schools. So when it's casted, there's a 2/7 chance that shield will benefit you. Does anyone want this instead of spell defying? But it's kinda tempting to keep defy because all the shields are -50% and may cast tower shield would be better since it's 100% chance to help you. I guess the cast rate depends on it, does anyone know how high the cast rate is?
