Okay, so I've been tinkering and tinkering, trying to find a version of a DD that could use 4 MG's and large AC's while taking advantage of the UAC jam chance reduction, while also having a Light Fusion Engine and not being ridiculously slow. I've listed some builds along my progress in Excalibaard's thread, "Optimal Prime", but I figured I've gone off reservation enough to start a new thread. Here's his thread, in which I include a version of this with dual UAC5's (underwhelming), and dual UAC10's (needed an XL): https://mechspecs.com/threads/jm6-dd-optimal-prime-2xuac5-2xml-4xmg-std275.12178/ But then I thought back to when I first built my Deathstrike. I was having a hard time with my 4MPL and 2UAC10 build being too hot at first, so for a while (until I got used to the style and also skilled up Operations), I ran it with one UAC10 and one UAC5. I thought of the weight savings, thought of this, then voila: _ In testing, it seems to be almost as powerful as the dual UAC10 version, but is also faster and has an LFE. You could also drop to an LFE260 or LFE255 for more ammo. The UAC10 and UAC5 ammo is balanced, though there are jams. There's enough LMG ammo to lay on them the whole time you're pounding someone with the cannons, and still have enough for the late game if/when out of big ammo.
