I was thinking it over a bit today. And if they want a squat and cast play style i think they could go a different route to encourage it rather then force it.

Just spit balling here, but what if they were to add something like steadfast stance for mages? Perhaps a bit of a bonus to say cast time, m.crit or potency while active. Something that you wouldn't need to utilize at all times but its nice when it is up.

If there not looking to encourage a style of play and are just reaching for a easy way to kill a cast, then i stand by my original facepalm.
