It's mid af. Relying on it means you're not good at the game. You won't grow if you don't use other things. Can tell you that the Heavy Plasma Incin is the worst heavy weapon, and somehow the most fun to use after you get it to Relic tier. The most entertaining weapon as a Tactical is actually the Bolt Rifle w/nade launcher. The Power Fist is fun as hell, even if it's awful... as the Assault. The Las Fusil class only has one option cuz the rest are bad. Vanguard is... well, it needs love, but the Instigator isn't bad. Gain some experience with other weapons, cuz bosses are gaining resistances to Melta and explosives. You'll not be useful in those circumstances at all.
