I would probably do speed and protection myself. Speed to go as often as possible to reduce his ultimate, and protection so he can survive until then.
He's the only droid on an HK lead team that I would equip with a speed set instead of a crit damage set even though he does have a pretty hard hitting basic attack with a high damage multiplier so it can get high.. I know that using covert operations will reduce his ultimate's cooldown by 6 (7 if you count the turn he is taking) and give him half a turn on top of it while his basic may reduce his cooldown by 1. So I would probably never attack with his basic based on what I see. Maybe I'm mistaken there though.
Now potency wouldn't be bad for his AoE expose, but when he has secret intel up he has 72% potency before mods which is plenty in general.
