I'm for increasing the duration of both buffs and debuffs.

I disagree with players that want to increase their duration indefinitely. They should be recast from time to time.

I agree with the players that durations should scale based on either a character stat and/or class rank. That way it gives players a means of "focusing" their Disciple of Magic character's abilities, and at the same time allowing cross-classes and characters focused on other stats to use those same abilities but to lesser effect.

My guess is this will be one of the areas addressed in the combat system overhaul. "Please look forward to it!"
