As much as I was hoping to be able to amass a horde of Assault Carriers with which to exact my terrible vengeance, I understand the choice to make it the Rebellion titan. It's similar in size to the Infinity so it makes sense. That being said, I don't know much of Halo lore outside the games and the one book I read, The Fall of Reach, and that was years ago. What other Covenant ships are classified as capitals in the mod? I feel like from the games, you don't see much besides (1) assault carriers; (2) Truth & Reconciliation-class cruisers (CCS?); (3) the Corvettes from Reach; (4) the modified cruisers with a similar model that show up in Halo 4; and (5) the Abomination.
I wouldn't be shocked in the slightest to learn that the Covenant lore contains ships that are still very massive, but smaller than an assault carrier. What other capitals do the Covenant get to play with?
