This is the only Shadowhawk variant that can duplicate the classic "AC20 + 3ML" Hunchback build. But the Hawk has the added benefits of jumpjets and more armor. The only downside versus the Hunchback is the reduced torso twist range.
On 2D many builds need to get rid of FF so I run this : I dunno if I'd drop JJs, it that makes this build unique and I want 3
The weak leg armor do not go well with 3x JJ though. And even 1x JJ is miles better than none, since that allows to to move through and across places. Here is a heave armor 2x JJ version. All at the cost of 1 kph.
It's a shame this can't run the XL, almost always exploding in the CT because of the hitboxes,even shielding I can't try your build because I miss the STD255, but so far I yet have to have a leg destroyed.
