To quote tdgood's training log (edited slightly for spelling):
"Before I get into the details of my run, lets talk (about) the map first.
* The circles and lines were not cut and hid several key features.
* There was at least one spot where the north line wasn't cut and went directly over a critical junction.
* The control codes didn't have the option white border around them and were very hard to see when they put them overtop of buildings.
* I am not convinced the building(s) were the correct color. I believe they are darker than they should be. I can barely see anything over top the building (like contours and the control circle/number. They had some purple hash(es) overtop a building which I didn't even see until someone else pointed it out to me (i.e. it was too hard to see).
* I do not believe the map was checked for legality. I believe they have several features which are too small or to close together to be legible. This is especially true of the canopy areas which they used extensively but you can't see them because they are too small.
* The dual level was used improperly. The dual level areas were so small that the symbol couldn't be seen on the printed map, it just made things look confusing.
* There are trail junctions that have the trail edging directly through them so the junction doesn't look like a junction but more like a badly mapped overpass.
* The Start was a remote start (which was ok) but the problem was that a change of direction was required immediately. While this isn't technically illegal it is a bad practice as you have people moving in one direction and then expected to change (to a different direction). The better fix would (be) to have the remote start just be a control for people to punch so everyone has to slowdown and the change of direction is (not) unfair.
* The first control on my course was used by many other courses (not their first) so there was an unfair advantage if you got there when someone else got there.
* The First set of controls for the advanced courses were in a building area which made the area very congested. Not only was it hazardous because of people sprinting around blind corners, it was slow if you got stuck behind someone moving slower (within a narrow corridor).
* The spectator control was unfair to the first runners as they didn't get the advantage of seeing people go to it like later starters."
I can't speak for most of the other issues that @tdgood mentioned, but the immediate change of direction comment does seem fair. However, I disagree about the comment regarding the spectator control. Everybody would be able to see it while entering into the competition, also, the spectator control location was revealed to be in that exact spot in the Event Packet on the bottom of page 4
