Depends. If you can 2-star it, yes. For a 1-star, an MLB SR assault weapon would be better because the skill levels are much easier to raise. Otherwise, a 1-star or less is only worth keeping around as a main-hand. If you already have an MLB copy, then the remaining copies don't serve that purpose.
