Well, we have unmasked another Death Eater, Avery. While it wasn't a surprise, perhaps he'd make sense as a target in order to send a message that it's not quite so nice and safe to be an outed Death Eater, no matter how the Ministry coddles them. There are also a few other recent unmasked.
Besides, Gawain's mum is still missing and any one of these vultures are likely to have been involved or know something.I can't offer much in terms of fighting myself at this point, but I could still track any of these people under disguise with my IDs, monitor their movements in order to strategise.
