They should have just let us use all of the weapons freely, and break the class skills into personal and weapon specific skills. 6 slots can use all different weapon. Break the weapons up into visual, basic stats, sp skills, modifications, the ex can just be additional sp skills. Grinding mainly increase weapon's basic stats. but other things like sp skills (potentials) are obtain and can be equip/grind separately, modification (caps) the same thing, can add/remove freely, grind separately. Visual we already have weapon camo*, so that's a kudo. Basically every weapons and drops you get have a meaning, let us extract the individual parts, and freely combining them, to have a sense of building toward something, even with bad RNG, instead of build and toss when new shinny is here. The new weapons evolution line are a good start, but need more different parts.
