Prerequisite Edit

Is there a reason to have a caster level prerequisite on this? Other metamagic feats don't have one, instead the spell slot adjustment prevents them from being used before some level. This would not usually be of much benefit before caster level 9th, though I see no reason to stop a 7th level cleric from casting Mass Resistance. -Cedges 19:51, May 30, 2010 (UTC)
