picking up broken formations if it's part of the activation of the unbroken formation, as it doesn't have the problems E&C has been pointing out
Actually, it does. Uncontrolled formation activates, self-breaks, withdraws. Controlled formation moves over to pick it up on its action.
Nonetheless, I still think merging at the end of an action is the best option. It's simple but has good implications for incentivizing reasonable behavior.
Merging a broken formation, which is getting the advantage of an effective "auto-rally", could only be done by a controlled formation as part of its action. The absorbing swarm would have to go out of its way to meet up, or the broken swarm would have to be pre-positioned where it can be picked up in some location that is tactically useful. That seems like a reasonable tradeoff.
To pull off the break-march trick, the Nid player would have to voluntarily lose units AND put the swarm into position, either a dangerous forward position or falling back. The absorbing swarm would still have the choice noted above. If it's an aggressive forward position, the broken swarm would be in proximity with the enemy, with all the attendant risks and disadvantages that entails. Activating the absorbing swarm ASAP would be a priority. If it's a fall-back, it would presumably be to meet up with some sort of objective-guard formation. That makes sense and even though it has less urgency, it would still require the absorbing swarm to activate to finalize the merge.
I can still see that potentially being a gamey tactic, but I think it has enough drawbacks that we can at least test it out before dismissing it.
If both swarms are unbroken it's easier but there's still a practical limit on the radius of merging. The uncontrolled swarm could position itself for a merge during its own action. However, it's going to be hard to make a big move with the Initiative penalty for being uncontrolled. The uncontrolled formation could really only count on a single move from either a faux-Engage or a Hold action.
