Now, I do like the job as it currently is mostly(Though I'm pretty sure I liked the HW incarnation better), but I do think that using a chainsaw at times as a gunner job would be really fun. I could do a great cosplay of Ash Williams from Army of Darkness. Hail to the King, baby!

Seriously though, I wouldn't complain about a chainsaw attack. I think it would be fun, or at least I always pick them as a weapon the rare times it's available, heh. Kind of like whips.
