I think what I'd like to see most for the Rumble, is Lesnar to be #2, and for him and Reigns to just start throwing bombs at one another instantly. Then when the 3rd guy comes out, they stop, and destroy whomever that is. Then, they go right back to trying to destroy one another. This keeps up until #8 or so, when somebody important(but not a likely candidate to win) comes out, and hangs around with them(Rusev? Jericho?) eventually Reigns and Lesnar get too close to the ropes, and are both eliminated by that person. Followed by Reigns and Lesnar continuing their fight all the way to the locker room.
I think the crowd would be 100% on board with that, because it would be such a huge surprise, without being a cheap one, because they basically got eliminated by being too focused on one another. Then the rest of the Rumble can be fresh, new and surprising, and that is what I, and I think most other people, want the most.
I just really don't want to watch it become the Roman Reigns and Brock Lesnar(and maybe HHH) are great, and everybody else sucks show. Which is sort of what I'm fearing.
