Partially a request for information, partially looking for a deeper understanding on how the system works.
So every weekend there is a single warfront that grants bonus rewards. My question is, how is that warfront chosen. Is it random? It doesn't seem like it, otherwise we'd see the same one in a row a few times. If it a schedule, why isn't it posted? And if it is, that'd be awesome and I'd conclude making a fool out of myself if someone could link a source.
A schedule would be amazing though so I don't miss my favorite WF.
