I like it Dual Heavy there are trade offs to each weapons in the game you just got to learn them.Between Beams and Cannons and Dual Heavy the Dual heavy is the best way to do the massive damage.Regular cannons are a little bit weaker then Dual heavy but they have a faster fire rate.So there is a trade off to each weapon in game you just got to learn how to build what you want like if you to be power full tac officer or a mindless healing drone or a tank there are different ways to go about this.If you are aggressive like me then i would go as either as a tank or a Power tac officer.Every thing depends on your playing style.
I use these be low.And i love them.
