Can anyone tell me when the Marian reforms happen in EB? I understand from the previews that there are two reforms (one separating early/late pre-Marian units; one Marius itself). But when do they happen? I ask because with 4 seasons, I suspect it is quite a wait and it may be frustrating to keep hoping for something that is a while off. Also, if there are any special requirements - like vanilla's imperial palace - can anyone tell me what they are?
