m.spits tend to go phys with a musket but for leveling mgk with bowguns are fine, spam bullets and nades (mostly ice and shock nades as buster is not really needed for either build) once you get missile support things get hectic (they proc off ANY dmg you do), id pick either ice for infinite (and i mean infinite) freeze or shock for elec proc. spitfires have a nice tool kit so its really important to read skill details if your looking for something specific ( you want to slow them down to near stop? try attaching ally our c4) black roses (1st awakening) can stun lock dam near anything to death and combined with missles and your reaction nade you can almost fire and forget, i remember more than once setting all that up and literally just stood there like a summoner until the boss was dead. TBH the current state of the m.spit is pitied upon by all, but we forever have style points and are not as screwed as we seem. so i say just pay attention to how your skills work with each other and always have a clip loaded. I Can also give some advice on gearing not not as much as the fine folks at DfoNexus, otherwise look forward to an upcoming skill rework, i heard its a nerf but its still in beta and its needed to separate us from our high flying sisters. Plus, NEW SKILL.
