I know for a fact there is a topic on these forums that mentioned that token items don't give UV's.

Barely makes it worth it since you can't sell them. You'd have such a large collection before getting a good one.

Gun charged attacks are also simply not worth using apart from the Alchemer's (for the split shot property) and the Pepperbox's (pull shot). Maybe something can be done to add utility to each gun's charged attack, possibly without even requiring new art assets... I'll just throw these out there.

Blasters: Have the charged shot deal wide splash damage or simply plow through enemies like the Avenger's charged attack. The bullet is big enough to make either of these ideas seem plausible. Splash damage can use a scaled-down version of the Blast Bomb's blue explosion animation. Ranged splash damage might be balanced versus the actual Blast Bombs by the fact that movement speed is harshly cut while charging a gun, the explosion requires a target to hit (or the bullet expiring), and that, well, enemies auto-dodge charged shots but not bombs.
Magnus: Charged shot could be a long-range, penetrating hitscan that leaves a trail of Brandish-style shockwaves in its wake (a sonic boom or something?).
Antiguas: Skip the five pre-shots and go straight to the birdie, or instead make all five pre-shots penetrate.

I love my pepperbox and all but compared to my striker it feels completely useless apart from the fire. It seems like the only way to do real damage with it is to hit all six bullets of the spray and the only way to do that is to stand directly in front of the enemy (try doing that without taking serious damage) and even then my striker kills them much faster. They either need to raise the number of shots, up the damage or make it easier to hit enemies.

I use my Khorovod and my Valiance quite evenly. The former is so slow the latter is needed in situations in which speed is of the essence and in case melee means getting surrounded, like in Arenas or Danger Zones. If guns were buffed, my Khorovod would only be unsheathed when I need to keep opponents at a distance - which would be almost never, as a shield does the job fairly well. The advantage of a gun to a blade is that at range, most opponents are not nearly as dangerous, making it somewhat safer than engaging in close combat.
