Heh, half-size Ferro/ES is one of those things that Spheroid players like to throw in us Clan pilots' teeth whenever the subject of inter-tech balance comes up. I know
aaaall about those things. ...T_T...
Anyways. I'm still trying to figure builds for the Executioner myself. My beloved pre-16th plan of a gigantic autocannon backed by eight crazy lasers was shot in the pants right the hell off by the lack of elbows across five of the thing's eight arm pods and also its intensely bad CT weakness and twist arcs. AC/20 'Mechs can't afford to be bad at twisting, they just can't, especially when they have no elbows with which to account for finer aim. Most of my current ideas are centering on the D RT w/2x cLPL being my Big Heavy Gun, with varying degrees of backup weaponry. Actually been eyeballing the D's left arm recently in Smurfy - 2x cSRM-6 is in no way a replacement for a cUAC/20, but with D left arm and A right, you get 4E/2M and also full two-elbow arm articulation.
Something like this. With the D torso pods providing hefty energy mounts, it
may be enough to make a better sorta-striker out of the thing.
May.
We'll have to see. It would, unfortunately run hotter than the sun unless I gave up the missile altogether for more heat sinks, at which point I'm carrying the sort of firepower a Stormcrow could match without trouble. Heh...though ironically, the Stormcrow may not be able to match the Executioner for agility when one factors in the crazed things M.A.S.C. can do.
