In my campaign, only the death gods can grant raise dead or resurrection. Nerull requires a life for a life (intelligent and equivalent not bag of rats) while Wee Jas requires a magic item of power suitable to the character level. Those brought back acquire an indelible mark singling them out as one of the returned (the mark of Nerull or the Mark of Wee Jas) but the dead cannot rule. Resurrected or not, lands, wealth and titles pass to your heirs and you have to start again. Stigma and blackmail fodder abound.
As far as building a warlord goes, if you adopt the idea of letting every fighter adopt one manoeuvre at will (without adding superiority dice to the outcome), enhanced by fighting styles and feats that give you extra manoeuvres, you could adopt a Purple Dragon Knight who has picked Commander's Strike as their at will manoeuvre, Manoeuvring Attack at will from choosing Superior Technique, and then Rally (at will for Charisma bonus temp hit points) plus either Commanding Presence or Tactical Assessment from the Martial Adept feat. They would only have 2d6 superiority dice but lots of fun with the at will stuff.
