Actually a very effective build! Not quite the CDR that LRM15s get, but velocity quirks help MRMs a lot. The low tonnage of the awesome makes it more maneuverable than the cyclops-Q.
Great build. Lost a torso early and ended with way too many missiles left. MRM 30 heat bump incoming Feb. 20 9 -> 9.5... eh. So expect the ghost heat values to go up in the future. Until then, 100 damage for 43.56 heat. MRM 20 6.00 12.00 18.00 27.15 MRM 30 9.00 18.00 29.84 43.56 Or 90 damage for less than 30 heat.
I'd personally fire Left and Right seperately with a 0.5s delay, and only alpha when absolutely necessary to strip as much as you can. Glad the build works out well for you!
