Wukong augment: increase his staff Critical chance
Valkyr augment: makes her war cry, that boosts her melee attack speed almost infinite
Baruuk Augment: increase his exalted weapon status chance
Excalibur augment: increases status chance and the elemental damage depending the color of the energy
Are you saying that all of this augments changes the play style while using them from melee to using primary and/or secondary?
You can obviously use those type of weapons for priming and else, but the play style is still melee.
That is impossible, if you want critical chance for primary and secondary, go use harrow's covenant....
