I'm out of it when it comes to defrag maps I'm busy with freestyle and fragging. I'm not even sure what map that is . From the screenshot it looks like another one of those stupid torture maps. If that's what floats peoples boats I can make you guys a map that can't be finished.
Go for it. But it can be finished and many people have done. Just make sure you get people to test and give you feedback before you release it! Torture maps are always welcome, any map for that matter. Just make sure it has a flow to it.....
