Hourglass was one of, if not, the most hated map amongst the community, becauce of its narrow design + base defences. That's the reason why no 1:1 remake found its way into RenX, but in form of whiteout, which is in my opinion way better. No offense but I guess the greatest part of players will agree here, while there will be always some people who prefer the old design. So to keep it short, the chances that you will see the original Hourglass in-game are going against 0.0
