Protect/Shell Duration Increase

[Keith_Dragoon]

I vote for a higher MP costs/cast time and a decent but not crazy recast on pro/shell without reduction in power. Increase the buff to 30 mins minimum and lets say about a 2-5 minute recast at about 150 mp each?

These numbers are just off the top of my head but definately don't need to reduce its effectiveness just to extend the duration.

Also to make things "fair" if the spell is used cross-class or casted by/on someone under optimum level the effect is 5 minute duration with a POSSIBLE reduced effect?
