Yeah... I totally screwed up when I was transcribing my army. Multiple times

. Your advice is all sound, for the army I posted, but it's not the army I'm building.
Also: the second Shas'
el is meant to sit in the backfield with the Broadsides, so his Bonding Knife and Shield Drones are also for their benefit. The only situation in which he'd leave that squad is if they were about to be assaulted and he had a chance to escape.
Let me try again:
