Absolutely loved this class. I've spent awhile looking through a lot of gunslinger esque homebrew classes but this is by far my favourite. The class itself nothing jumped out as massively broken, I've made a couple of slight tweaks but If a player came to me with this as is. I would have no problem with them playing it. Definetly got more substance to it than the standard gunslinger that's a dime a dozen all over the internet. Only critique is i would've liked the subclasess to be a little more Smith themed, like the grenadier (which in my opinion is a perfect example of a gunsmith and fantastic class for a player)
I would definietly check this out, mainly because if you've got more than one player that wants to play a gun toting charecter, this is a great option to help make them unique and different.
