Add knuckles and guns to Mo's shop

Description: Currently, gear progression for Pirates is incredibly bad. Buccaneer & Thunder Breaker have the Astaroth Knuckle and crafted Knuckles as their only special weapons, while Corsair has at least Astaroth and Bain weapons alongside crafted Guns as their special weapons. Why I think this is needed: The severe disproportion in gear progression makes Pirate and Thunder Breaker an extremely unfavorable class, due to their damage output dramatically falling behind by lacking these key upgrades. Prior to the Superior Regions update, this left Buccaneer & Thunder Breaker with no clear upgrade between the Astaroth, Maple, and Unwelcome Guest knuckles until they finally hit level 120 where everything starts having options for Knuckles because it's crafted. While Mo also sells various omni-class weapons, this is a massive detriment to all Pirates and Thunder Breaker, because most to all of their offensive skills explicitly check for their weapon type. Despite the Stirge balloons being wieldable by Pirates & Thunder Breaker, it leaves melee Pirates with only Sommersault Kick while leaving gun Pirates with... Basically nothing. Possible Downsides: People will be enticed more to play Pirate Extra Notes: I also think it would be a good idea to add a Bain knuckle to help newer/poorer players since Mo's gear is extremely inaccessible to newbies/lowbies thanks to the extreme price tag. Mages are looking at a 256 million (256,000,000) meso price tag to fully max these gears out as you're expected to just to be as best geared as possible at level 60, not even mentioning level 120. Generally, you won't start being able to more reliably make millions of mesos until you reach the Cave of Life zones of Minar Forest and can kill them with relative speed... Which is a challenge if you don't have decent gear to use.
