Okay, so I put missiles all over the all-universal Conquest, and it was okay. Still not enough missile-y goodness for the OP, in my opinion, and it kept trying to chase after ships to attack them with the PD lasers. However, I also tried a build with heavy blasters and plasma cannons on only one side, and that thing can solo the SDF.
Anyways, my point is, even with a ton of pilums and MIRVs firing all the time, the results were less than spectacular. Versus an Onslaught, even with all missiles firing, only a few reached the target, only to hit the shields and do nothing. Smaller ships just dodged the missiles.
