Hmm, Odd, I thought I made a whole long post yesterday about this.
Wonder if I posted it in another thread or if it just didn't save, LOL.
Well, basically it was this.
2 Heat & 1D6 all the way.
Even w/ those negatives it's downright Awesome........why?
Because I'd replace EVERY SL on every Awesome with it.
And Hunchback, Urbanmech, Locust-1E, Griffin-3M, WarHammer-6D (6R/6L), Centurion-9AL, Enforcer, Cicada, Banshee, Catapult-C4, and HALF the SLs on the Charger.
This thing as is, would invalidate use of the SL on "almost" every design it's on.
The simple fact that it is 1/2 ton means the SL, MG, & Flamer are all in danger of being replaced.
So no, I wouldn't make it any "better" by reducing heat or boosting burst.
Even w/ it's "flaws" you've basically got the META choice for 1/2 ton use here, it's the "Medium Laser" of "Half-Tons"
