Yah I have a bit concern about that since core engie can use only 1 mh weapon and 2 oh weapons so if we get a new oh weapon, we have only 1 mh choice and if we get new oh, it's gonna be like holo and we may end up using engie tools like the same.
I really expect to get a 2-h weapon for higher choices for weapon skills like greatsword or staff. Both of them can be either melee or range, physical or magical depend on the elite spec mechanics.
