imo

Redirection (priority 1, high shield = as close to invincibility you ll ever gonna get)

Vitality (infested and some skills can hit HP directly, also usefull if u fall into a cryo map (half shield))

Rush - along with Marathon (cheap cost), and Quick rest, can give you almost perpetual sprint

Focus and Streamline (i usually sacrifice a skill i never use to have both, altough if you want to keep all 4 skills, i might suggest depending on your style Focus if you save your Energy for special occasions, Streamline if you use your skills often
