Just something I came up with tonight when trying for a reasonably-priced improvement over the stock BLR-1G(P). Alternatively, the ERLLs could be downgraded to regular LLs, improving the heat efficiency to 48%, or one could drop one laser, one DHS and the MGs in favor of an AC/2 with two tons of ammo.
I saw your build last night, and came up with this for my 1D. I liked it, so I made a 1G version as well. Obviously, I try not to get in a knife fight - but when it happens, there's something about the flamer/MG combo that really backs people up.
My problem with this idea is that the Cataphract 3D does this job almost as well, but jumps. Edit: Just pretend that it has 2xERLLas in the side torsos as opposed to standard ones, and that the cooling is 42%. And can even do it faster (ok, it can't cram a flamer onto it, but still). I don't think that the extra armor (and a little bit of cooling) is worth the 15 extra tons of 'mech.
