The Tarn/R7 combo is one of those I want to try, but just haven't been able to get him on the table yet. However, for those who've tried it, I'm curious how you handled the defensive target lock, especially against enemies that have a focus token. Do you force them to reroll all hit and focus results, hoping to see another blank or two in there? Do you leave the focus as is, and hope you're forcing them to spend the token and making them easier to counter-attack?
Or is it more situational (reroll focus if you don't have a shot, keep the focus if you plan to attack them)?
Just curious exactly what the best tactics are going to be for when I finally get around to flying him.
