Energy weapons seem too light for a no heat system, the 24 jumps with jump jets is hardly a limitation in any typical game of Battletech, and the inability to generate a positive move-modifier basically ends the value of lighter units for all time. I guess if what you aspire to is SitTech, then you're closing in on the ideal. At this level of modification, it seems like you'd be better off picking up a copy of Dirtside II as mentioned above, or dare I say it, CAV.
