Quick and Wild (Desperado) does not fire all the rounds of a gun it uses, despite the skill saying it does 'a basic attack', which is expected to behave this way.
Not a bug I think. (Repel/Hanging/Pinball all behave this way) but for the same argument as parting shot, I think it'd be cooler if it used your gun's rounds instead.
Still this is expected behavior mechanically speaking.
Ain't no way this isn't a bug or oversight, otherwise Parting Shot wouldn't fire all rounds, nor Steal's Trickery Effect would either, since all of those "perform a basic attack with your gun".
The reason why it doesn't unload on a Hanging or Repel is because those skills are not tailored for guns in specific, while Wild and Fast is, in fact, a gun skill made to be used with guns.
Either way my dear cookies, my DMs are open to discuss what is a bug or not, this thread's purpose is to report, not to make an unnecessary discussion so let's not clutter it and I get bapped again by boss man for not giving enough helpful info, I'm on strike two. ;-;7
