15 points for a 3" melta range? If you're that close you're charging, and so long as it's not a Walker you should survive with Krak grenades. Normal Melta Guns still get to shoot Overwatch, and having an extra attack in CC is cool and all but I'm not convinced. Where would you fit them into the list,
? Typically I play my Melta RAS Sergeant with a Power Fist and the squad deploys via Drop Pod. Love that shit.
