Could you share your reasoning behind large cycled missiles, they are generally accepted as the worst even though my experience with small missiles says cycled rocks.

Using large missiles is for killing armor tanks with blasters. While the Accelerated do more damage, initially, and can land the missiles more accurately over distance, if the armor tank closes with you, then he has a chance to out DPS you in the initial bout. What you want to do is welcome him into your arms. The cycled missiles shoot more often, and much faster than any other varient, and over the course of an engagement, it adds up, significantly. If both tanks are at full health, the blaster tank will have to pull back because he can't shoot you, enough, and you just follow him very closely, raining missiles on him. if you are fighting an armor missile tank with anything except cycled, you will notice any advantage that their slightly more powerful missiles give them is lost when you close the distance to a knife fight. Believe it or not, the cycled missile launcher out-DPS's every turret available...if you land every shot, which is why getting close is key.

However, equipping these missiles will make you almost useless against infantry, so keep that in mind and roll with a buddy who has a blaster.

Keeping all this in mind, it will not do wonders on a Falchion. With the falchion, keeping your distance and using damage mods and nitros is what will win, because they cannot close distance, tank damage, and disengage fast enough.
