I feel like unironically agreeing with those who felt that Kagura getting stripped was the best part of the chapter, and even that pissed me off (both for Kagura falling victim to Defeat By Modesty and the random fodder mages stopping to ogle her in the middle of a warzone). Honestly what makes this chapter so terrible for me is that interesting stuff happened (Brandish locating and shrinking the tumor, Saber, Lamia and Mermaid's retreat, and the Wizard Saint battle), but we just didn't see it for some reason. The best I could think of is because it's easier to leave it to your imagination so that when FT stomps these Spriggans you'll have no one to blame but yourself for hyping them.
I'll give props for two things though:
One, Aquarius telling Lucy what she was going to last chapter instead of leaving it hanging (too bad it was just repeating what she said earlier with more words and it took up panel time better spent on the actual fights).
B, Judging by Makarov's conversation with Poryluscia, Brandish may be the mole but there's more to it, since her actions confound even Makarov (who being the one who theoretically put her up to it, should not be confused).
