so, heavy flamers are 20pts and i wonder why.

im not moaning i just wonder if there is something i have missed using them? its basically a normal flamer (assault template) but with +1 S and -1 AP. is there another reason why i can get 4 S4 AP5 flamers for the price of one heavy? its only gonna instant death T2 models who are all 1W anyhoo so its not like its S6 or anything.

my point is it seems expensive for what it does compared to the other special and heavy weapons that seem very cheap indeed. is it more badass than im realising?
