Clones without Clone Sergeant for Heroic AAT?

Cody's 212th attack ability (in combination with the zeta) will be gimped if you don't have 3 other clones. So less clone crits, the less often you can use that ability, and less damage overall. Plus Sergeant is the biggest damage dealer in that group if you look at any of the P2/P4 videos/screenshots people have posted.
