Oh, MWaP 4 becomes +12 to plotting rolls, 7% chance/W of a free mission, and a +4 to all rolls in plotted missions.
Furthermore welcome back Comp.
I agree about Plotter, it just feels to me like certain areas should be approachable in a Leader Does X action fashion, and others are more passive. To me the flavor speaks more to MWaP, your minions approach you with ideas, and you cut away the clutter and streamline it, sort of deal. Whereas Researcher feels like its the more hands on thing, as any evil genius dabbling in sciencey things tends to get their hands dirty.
Frontline Leader has some possible directions it could be taken. I'll certainly give that some thought. I may in fact base a future archetype around that sort of idea. (What, you thought those were my only archetypes? Please!)
Master of Mayhem(in that structure) seems to me to be the sort of thing I'd allow at a certain notoriety point, freely. It speaks to me of the kind of figure who simply has the clout/capability to call up the World Leaders in conference, and deliver threats and demands.
I mean certainly the end game would not be complete without the ability to call up the world leaders, say you have a device that does X and you are prepared to use it if they do not surrender control of the world, to you.
However on a smaller scale, Mayhem would be the sort of thing that flavor wise, it would make sense to allow. As its not unheard of for the leaders of evil-type organizations to take an active part in murder, destruction, so forth.
