To be honest, the Idea with Swiching Weapons is a cool Idea, but its kind of pointless in Combat, since you can't change Weapons while Fighting. As an Idea for Crush 2.0, maybe split Weapons and Classes. For Example there is a Saint with the Blades and (maybe) a Wizard with the Staffs. With that in mind its possible to split the 3 already existing Classes in 6. Now to the Weapons Swiching Mechanic: As i said before if youre in a fight, and you dealt some Damage, or you've been hit you can't change Weapons untill you waited 30 sec (or so). With 6 classes however, it is could be beneficial to remove that Swiching feature, however different weapons , can be equipped, but only 1 at a Time and only out-of-combat its changeable. Or keep the Swiching Feature and make the Weapons Swiching with a lesser Cooldown, that even in a close up fight players can (after 10 sec or so) change Weapons.
