first i just want to correct all 3 of you and say its the RAMPAGE not the dragon, the dragon is a light ammo LMG that is not out yet.
that said this gun may be able to do a good chunk of damage but it does entail a certain amount of timing, and aiming. you can get melted using this gun just as easily because its rate of fire is so low. yes a thermite speeds up a full mag and some but thats likely a low hit rate for a good majority of players with poor tracking skills. not everyones at pred/masters levels. you can do similar damage with a single fire hemlock if you have better tracking, and has a much faster rate of fire.
