Can’t give a black and white answer to a grey question. Reality is that MOML means whatever the orb owner wants it to mean. They got the orb and the right state their terms for its use.
That aside, the whole concept of an orb to play a dungeon that is already time gated is dumb. We really don’t need/never needed this second artificial limiter, devs. Progression is slow enough without it. It’s redundancy just causes unnecessary heartburn.
