Can’t say for sure, as I’m not the TL, but I assume it’s because the volume chapters are markedly better in quality. Soms other groups, to my knowledge, actually also use the volumes, but purposely stagger their releases to give the illusion of a regular release schedule.Insomaniac translating Insomaniacs, ironic.
Thanks for your translations! @heynow Is there a reason you translate only by volumes, not aech chapter ike most other groups?
