The difference is minimal. Infact if your gear was up to date you might actually be better geared if not synched.

As far as war is concerned overpower all the things and you should never have a problem with aggro. Maybe put some points into strength if you are stacking vit. Adding flash into the mix helps as well.

Pop bloodbath for some extra aggro as well(the self heals also add a bit of enmity).
