I do know, when your leader is feared or CC'd, the other toons cannot read her target.
So if your current lead is say Cycloned, then regardless of what they target, the slaves cannot read that.

If the leader is feared, but the slaves are not, the leader is useless for targeting.
Not sure if that's your issue.

You can change your macro's a little.

#show Lightning Bolt
/targetlastenemy
/cast [target=focustarget] Lightning Bolt

Even if your leader is feared, the slaves will at least cast at someone.
