I think it deserves more than 3 stars. For it's role it is pretty good. This thing is designed to chain fire missiles. Now if only it had tag or Artemis
I have thought a few times about shifting one of the 15s to a 10, cutting a ton of ammo, and ditching the rest in armor to get the Artemis in. More testing needed!
Here is a twist (actually built from scratch before I read this post) ... The smaller XL210 sacrifies some not so much needed speed and allows the addition of TAG, BAP, two machine guns and a Medium Pulse to replace the two Medium Lasers. Now, I really do hate missile boats, both to pilot and as opponents, so I don't know why I made this build. But I did ...
Chainfire the missiles! Alternate "Super-Ammo" Version: 4 of 5 from me for the impressive indirect firepower, though i find it runs a bit hot for sustain fire, which was a reason for me to run Quad LRM10s http://www.mechspecs.com/forum/index.php?topic=3281.0
Artemis can be fit easily by downgrading two of the launchers to 10-sized ones. As a bonus this version also bypasses ghost heat when going for full volleys.
Seen that the missile spread on LRM 10s is vastly more efficient than the 15s, I have always used the below build. Which has totalled me a K/D ratio of 1,46 over 235 matches
