Forum:Does the Piranha Shotgun render Melee-Vanguards obsolete?

For any single-player Vanguard players here: does the Piranha Shotgun render melee-oriented Vanguard builds obsolete? I've recently started a new playthrough, wherein I originally intended to create a brawl-and-Lash Vanguard character, though I'm no longer certain why melee attacks are a good choice of tactics or a good choice of character builds. Anyone here have any views?
