I actually just started playing and I have a level 9 version that I pretty much use to 1 shot badasses, which I do agree, makes it awesome. Was just wondering why it was better than other Tediore weapons. I didn't notice the smaller grenades... i'll check again when I get home.
I had a lvl 43 baby maker at first. I'd one reload kill almost anyone with it. Only real big guys or bosses would take more than a single reload. That's why. --- I have Dysarthria. It's a Speech problem. Your question is answered now.
