I have a problem. The middle point is used so that engies have time to set up. If there is no middle point, then they will arrive at the second point just before the enemies do.
To counter this you would either need a long run between points 2 and 3, roughly the time it takes to cap a point, or a area in the middle that encourages blocking other players and creating time to set up.
But if you have those, it should be fine, otherwise, it just becomes a comp to see who can get the most players on the point the quickest.
