try taking the settings off the "im a whining baby level" and come tell me combat is easy. For example default is 1/2 damage to your troops, 1/4 damage to you you have the combat speed on slowest, combat ai on poor and campaign ai on poor . all the worst settings.

also nords are my favorite faction and are very very strong. best melee archer in the game and the huscarl is the best infantryman in the game.

go try to take a castle from the nords and see how long your troops last on the walls.
