Maruaders are quite squishy so I would suggest better armor probably a Rus Helm because you'll still get one hit from ranged weapons (Rangers,Huscarls) but it'll reduce melee damage taken from the head and Heavy Plated for extra cushioning against hits . Your throwing weapon won't really matter much as you'll be primarily slashing so you can pick up a throwing weapon if needed. For load out I would suggest you bring a Sarrisa and another slashing weapon depending on the circumstances but upgrade your German Poleaxe to something with better cut damage (speed Doesn't really matter because of your pole arm proficiency bonus). In conclusion, save up for better gear, buy a better poleaxe/halberd(Swadian Poleaxe,Swadian Halberd), and don't worry about your throwing weapon.
