The Ash Factory: One super-powerful, high-radius/damage rocket with low velocity. Pair it with Tripod and Tracking to remedy small magazine and velocity problems (Velocity is the speed of the rocket). Although it has a low rate of fire, it doesn't really affect long range or Guardian-advantageous engagements. Tracking doesn't give it high velocity, but makes sure the rocket almost always hits its target no matter how much velocity. The low velocity can actually be helpful, because the low travel speed of the rocket makes for more accurate tracking. In the minor Perk trees, I apt for reload speed, blast radius of you can get perks to increase it (already beast), and definitely rate of fire. Higher ROF makes for quick, devastating damage to your target in successive bursts. A pause for the reloading process, a moment to acquire tracking on the target, and you can repeat the process.
