i would also like to help if possible.never looked into the waypoints and stuff yet cuz they dont work properly if ya dont do the study bit(resetting waypoint events and stuff bit complicated on me poor brains but i can learn)but i know how to make balanced maps with proper gameplay.
u can download my(bhd) mappack early versions wich have been played a lot as example.
i know most of em dont have psp's wich i put in after the mappack was made for download and i never updated it afterwards but its 5 minutes work to put in the psp's.
