I.. what?

Did you boot Diablo and immediately regret that you couldn't have Epics right off the bat that fit your playstyle? You're a starting inquisitor, a low level character, and the new setup has been great for learning how the weapon skills and weapon types interact with each other. For example, if you're a heavy and you're not using that lasgun against ranged mobs, you're most assuredly doing it wrong--the shotgun should be your melee-enemy clump shredder. It has the same range as the boltgun and heavy bolter, even the starting weapon starts off with plenty of firepower to handle the first few missions until you've leveled up enough to replace it with a plasma gun (which is now viable and working as it should be, if you take the time to read the skill tooltips and run a skill rotation). The heavy flamer should replace your shotgun as the melee blob melter, and it adds some really nice CC to the mix in the form of area denial and that long range blob of promethium (that even works against elites rather nicely, if they're not armored).

To quote your other weapon post... This isn't Diablo 3.
