Actually I think Prochnyi is almost always the best one for light bipedals, just need to make sure you have 3,300 or more energy output. I think it has to do with how the energy gauge fills faster the closer it is to full. Just test them out and you'll see I think. It'll be even better with the patch that buffs the output. edit: no way I could use the pulse gun effectively with a Ho Vital anyway Yeah.. I think it's just a bit too hard to do hit and runs without taking any damage with the cqc weapons this build uses (pretty much impossible vs gatling guns). Not that you can't make a close range LW work well, but I do better with a dual shotguns LW build than this. As such, turned the build into a midweight and added the amplifier back, performs much better for me and more practical outside dueling: Inhert M Hi Mbl Close Range Medium Bipedal HEAD UHD-13 Galahad CORE KT-304/Xiezhi ARMS EMS AM28-2S LEGS ULG-21 FCS UFC-11 Glance (chosen over yasakani to save energy + add computation) GENERATOR KV-3D3/Prochnyi BOOSTER BT-21 Shinatsu RECON UNIT URD-36/ER (350 range tracking) R ARM UNIT Zinnia SG54 (shotgun/power) L ARM UNIT KO-3T5/Mahaon (pulse gun/power) SHOULDER UNIT UEA-4 Izanami (EN amplifier) R BAY UNIT Sophora BHG16-2 (Handgun 3R burst/power) ^ to stun enemies before firing Mahaon once Zinnia has ran out of ammo, will be better after patches @wktk yeah, it was mostly to get in and out of that range for hit and running (again, USGs etc) and it seemed like the most practical choice for the weight left, though I didn't want to use flash rockets anyway.
