So this is basically the IS version of the great Timberwolf "1.30 Second" Build. You give up a lot of agility and range, but you do have about half the laser duration which helps with targeting components, and the MLas get quite a nice boost to their quirks.
5/5, This is quite simply a great mech. Very tanky arms, hits quite hard, Still has half of its weapons after losing a torso, full armor even on legs, and perhaps the best 6 high mounted laser hardpoints in the game. With the cooling, tanking, good speed, great damage potential and no ammo limitations this is a great mech for CW.
