5 Major changes that could happen after Brock Lesnar's WWE Title win at Day 1: 2 changes to WrestleMania main events, Surprising star to win Royal Rumble?

#1. A world title unification match between Roman Reigns and Brock Lesnar at WrestleMania?

Roman Reigns vs. Brock Lesnar at WrestleMania 38 could still happen. But this is one scenario we certainly don't wish for at all. This scenario involves WWE booking a world champion vs. world champion match at The Show of Shows, with the winner then defending on both brands.

This isn't a good idea at all. The company still has a big roster that is split over two brands - and that is a system that benefits fans and the talent. More superstars are allowed opportunities, and having only one world champion now would severely restrict one brand or the other.

WWE is also being paid good money by both FOX and the USA Network for their broadcast deals, so it makes sense to keep two world titles. Lesnar will likely stick on RAW, and hopefully, there isn't a scenario where the feud with Reigns continues.

With that said, the only issue this causes is that the intense rivalry between Roman Reigns and Brock Lesnar could now abruptly end without much of an explanation.
