Yeah it's the very least that could be done to at least get some use out of the other type of weapon in the same lvl for each class (i.e. axe vs aeg, dagg vs bow, staff vs gun) and turn it into axe+aeg, dagg+bow, staff+gun. Also, to not diminish the value of the other weapon (just like how dugg bow now is dirt cheap and dugg dagg is just through the roof), it would be great to have a synergy between two arc weps of the same class only at the same level to prevent the same thing with really old gear becoming necessary since now you won't be able to stack them no more.
