I'm with Tom on this one, to me this isn't defrag. There's basically only the effort of remembering the route of the map, which in itself could be fun for first time. I only saw 2 OBs, in a map where every 2nd jump is a fall...
Defrag runs are supposed to be nearly flawless, this is flawed in many aspects, i notice humanly errors as if this was 1st/2nd attempt at this map. And that already makes it flawed.
Another thing is, if any of the top runners actually bothered to figure this clusterfuck out, there would be many cuts that save on time, much more OBs, certainly much more acceleration.
There was only one of those climb-runs that was actually good, some guy who took the effort to complete the map that had half the spots invisible, towards the end it gained pace too, so i can appreciate that.
But the more i see those maps the more it seems like the people who make demos of it can't compete with the very best with their obscene corner clipping and acceleration. So they pick maps where it's almost not even needed. And gain the WR at it...
Because no-one ever played it other than that guy.
