I say this at a risk of marauder adjustments.

Are there any drawbacks of using Rampage now? Memory might be fuzzy in transit. It seems like something we would just keep on. And once we start getting hit again while stationary, receive its benefits. No need to recast it when we move.

Berzerk: marauders are to have lower defense. Consumed with Godsbane.
Fists of X: consumes MP overtime.
Cleric's Stance: reduced healing.
All others have a limited duration with a recast time.
