That's why I said 'usefulness' because it seems to require an awful lot of planning or at least circumstance.
Not really. The scenario I posted with the 3 named pilots was just a proof of concept.
Having a focus and target lock at the same time isn't hard. The scenario I posted for getting 2 focus tokens and a target lock is a fringe case but getting 1 of each is easy and being able to use target lock instead of focus to increase torps' damage is a decent improvement.
If they make a secondary weapon that uses target lock but doesn't get discarded, this card could be amazing but seeing that possibility doesn't take any foresight.
