i agree go with your primary weapon attribute.....after you start gaining some levels throw some into tactics since that has your only warrior class self heal...plus it has awesome stances/shouts you can use. as others have said you can change your attributes at any outpost or town. if something doesn't seem to work well...go back to town...readjust and try again.
