I'm building a map that has almost the the exact same concept as all of these but it serves a well purpose as and obstical.
I was having trouble coming up with a top mid of my map and I thought of this thread. I didn't include a kill ball because the thread title told me not to. My map is now eight and two fifths times better than before. Should play super awesomely.
Thats great stuff =D I'm so glad you didn't put a kool ball atop of that, it woulda totally thrown off the map.
