1: Make more of the existing traits, utility skills & eleite skills worth using/comparable to the ones meta builds use.
2: Create new weapons types.
3: Make more of the existing weapon types avialable to more classes.
4: Make new utility & elite skills.
5: Make cross profession utility skills (IE skills that all soldier classes can use, skill that all advendurer's can use & skills all casters can use).
I'd love some of these to be done progressively in the near future in a monthly update rather than all in one big expansion.
