Late poast is late but imma add this:
Double gunner would be kind of moot due to the way guns in general are in the game. If dual wielding guns were to follow the same rules as pirate's dual swords (offhand gains only 35% of the stats and attack), it'd be a waste as guns do not provide that much stat wise to warrant dual wielding. With pirate's dual swords, a high +'d offhand sword still gives a significant +VIT and STR boost. Guns only add dex, which is a scam.
That being said, a B class gunner is coming anyway.
