They halved the price in CA so its down to 5 now which is still crap since you need about 9 to average 1 wound per turn. Not going into the math but trust me it's still crap.
So here is my proposal.
Why not change its gakky you get a very terrible chance at a single mortal wound on a unit that is so close you might as well be in CC with them to all weapons with the flamer type are able to fire up to 12" for Overwatch.
What do you guys think?
