I'm saying chuck something in that is easy to stomp so we can treat it like a daily or burn it out of the way ASAP and move on to other stuff. Since we're not going to be getting any new gear out of it, might as well let us steamroll it so we can move on and reduce the required monthly workload on the devs so they can try to get something else done. Honestly, from the way they make it sound, it's not actually easy to rotate the mobs inside, so why bother? Especially once the announced new content is live, there is little reason or precedent on continuous updates to old battle content, so again, why bother? If the only changes each month was rotating the purchasables, they might even manage to automate it so that no man-hours would be wasted.
My gil is on Omen lockout being reduced by at least half in the same patch that the new content is launched or within a few months after.
