I agree with Mercworks, the DC isn't a dedicated brawler. I run it with AC5's+cooldown modules, LRMS10x2, BAP, and 2 medium lasers. It doesn't seem like it would be that effective, but it is. ECM (pluse radar derp) helps keep you from taking nibble damage from SRMs and LRMs. The atlas is just not seen as that big of a threat when compared to: EBJ, TW, DW, WHK, or KCrabs. You can put down a lot of damage from the AC's before you start getting focused on.
3 of my 4 Mauler builds are AC20 builds. The other is ac5x3 build. You have a lot more hard points for various builds and high AC mounts in the torsos. I doesn't seem to tank as well as the atlas imo, but it can put out good DPS. It is hampered by its lowly 325 engine cap. The MAL are XL engine friendly, but with a cap of 325, you can't get to the 340-360 sweet spot.
