Bolters or Bolt Pistols are just so much better though. Every model needs to get within 6" of an enemy to hit with the hand flamer, ...even if it went from D3 to D6 hits (did it?)... it's still only S3 also.
Mathhammer is all good and fine except when it comes to drastic Range limitations and limited opportunities to actually use said weapon.
No, still d3 attacks.
I'm using them mainly since I modeled some and they are relatively cheap (actually put 2 wounds on a biker captain yesterday with a hand flamer, but that is pure luck)
