I don't hate fatal melter

2-Shot kill and fast firerate. Just throw a level IV shrapnel module in there, and you're set to spam.
Oh yeah, and you can rocket jump with it. Just don't shoot the walls.
Ummm.... Getting a level four module takes quite a lot shards, in my opinion.
Personally, I think any weapon with high modules will have a very fast kill rate.
You should have at least a few level II modules stashed away somewhere in some random guns(or at least I do.) by the time you have a few level IIIs. I usually just extract instead of upgrading extras. Saves shards :p
What do you think?
