I started with 6 AC5's, but the heat penalty did kick in a couple times. Now I have plenty of ammo and even better DPS.
5/5, Great build. With the new patch, I never overheat and can put out pretty decent damage. This was from my 2nd game with the build. Did 596dmg in the first match.
5/5, The different velocities may be a problem for convergence, but the increased DPS and alpha of this variant seem very powerful indeed.
