4e Martial is "not magic"I'm more into power source refinement.
Like Martial is War. "of or appropriate to war". That not roguish. Rogues cheat. Fighter, Rangers, and Warlords fight.
I'd pull Rogue out of Martial to make a Subterfuge or Underworld power source with Swashbuckler (defender), Boss (leader), and Saboteur (controller).
Then make Arcane pure knowledge based magic and shove Sorcerers with Benders and Shair into an Elemental Power Source.
