Kinky.
Also I have a question: Is setting fire to a ship really that important that you'd carry incendiary rounds instead of something else?
It's just that as an engie I've seen fires set off in 3 (maybe 4) different parts of the ship at a time, max. (or maybe I haven't really faced an extremely fiery opponent yet. Get it? xD). It's also easy to take any amount of stacks with the fire extinguisher, which you can quickly switch to if you see one of the other team's ships has a lot of fire starting guns and its crew has the ammo. And in general it doesn't seem to cause that much trouble.
Again, I'm still pretty new to all technical stuff so I'm mostly sharing what I've seen in my little experience and waiting to be corrected
[*happy face*]Edit:
Well it can work on a gatling. But it totally depends on your enemy.
IF you fight sth like a mobula u can bring it so you can distract 2 engineers with your shots gaining fire superiority quite easy.
And a incendiary gat can still shred a mobhull.
Well that's one good time to bring incendiary then, thanks! xD
