I think the women's rumble was better than the men's rumble. I also felt that the women's war games match was better than the men's.
This could just be because the women are really talented and are just going to do better than the men sometimes. But, I think a part of it is also because on both of those occasions the women opened the show. It's really hard to have two of those kinds of matches in one night and have them both have the same impact. The men's rumble just kind of felt a bit off, and I think that's part of the reason.
For the rumble, you kind of have to have both at this point. It's such a tradition that people would revolt if there was no men's rumble and it would feel like a huge step backwards having no women's rumble. Similar for MITB.
But for the other events, war games, elimination chamber, hell in a cell, etc., I think going forwards, they should just have one of the featured match type. Men or women's whichever makes more sense with whatever's going on at the time.
For the rumble itself, I think having both in two nights makes no sense but like I said, you can't eliminate either. So, why not do them on separate nights? Not like Mania, but have one Rumble in Jaunary, and another in February. Marketing may be slightly tricky, but I think it will make each rumble feel better, and they get to use the Rumble as a selling point for two different events. Seems like it would work better that way to me.
