I’ve designed similar ankle-biter specialist BA, so you’re not the only crazy one. Leg attacks are better than swarm attacks, so it makes sense that a suit or two would be designed around them. I used the same combination of BA Myomer Booster and Vibroclaws on a non-jumping medium suit.
That said, you only get the damage bonus from the BA myomer booster once. Spreading the booster across different sections doesn’t double or triple the bonus.
I’m also not sure whether adding a second vibrio-claw doubles that damage bonus or whether you can only get it once, too. Someone more familiar with the vibroclaws rules should chime in. If I’m right, then you definitely only want one vibro-claw.
So I don’t think there’s any way to reach 16 points of damage for a leg attack. That said, leg attacks are really about the chance of inflicting actuator critical hits (not raw damage), which I think a vibrio-claw helps with. (Again, someone who knows for sure on the rules should chime in.)
It’s min-maxing, but you can make these knee-capper designs more flexible by using a Spheroid chassis, which saves 75kg. Dropping one of the vibroclaws frees up another 50kg. And you have another 70kg tied up in fixed Improved Sensors, APWMs, and Mission Equipment, or something approaching 200kg total to work with. I usually add an MWM and an SSWM and use combos like Micro Pulse Lasers and a Light TAG, Flamers and an Improved Sensors, Heavy Machine Guns and an ECM, or Light Recoiless Rifles and a Searchlight.
Hope this helps.
