Use heavy mid legs if you like heavies, the S3 legs are gorgeously buff. Shade will beat the game with ease, everyone is right. I used a build like Shade/69h or blade depending on the mission/starter missiles/gaea core and like macaque, cougar 2 legs and any of the good heads with radar, high ecm and bio sensor. Also relation missiles rm3 or Gar. For normal missions shade and gaea win, and for missions with ACs shade and gaea does the job, toss in a couple supported missile volleys and its GG. SHADE is one of the few weapons that has the distinction of being fantastic in both human vs and missions.
