In the end, some proportions just work better than others and forcing stuff into a rectangle can lead to some complications:
- 1: Is it really the best thing possible that it is very hard on CK to form a defensive concave on top of your own ramp. Did the author intend this, or is this a concession that had to be made to force the map into a rectangle?
- 2: Was it really the intention of the mapper to make it hard to get a defensive concave as someone approaches through that choke (it's very hard for instance to stop a sentry/immortal coming through there). Or is that just something that had to be done to force the map into a rectangle?
- 3: Was that really the most optimal way for that passageway, or again, is this a concession that needed to be made?
Taking another example.
- 1: Again, a really long path where no real defensive concave can be formed. The third of daybreak can be particularly awkward where a defending player coming in from the natural may find himself against a concave of the attacking player.
- 2/3: I feel this area in general just doesn't flow in a very natural way.
I do feel these examples illustrate how maps become awkward, primarily at their edges, because people try to force them into rectangular canvasses a bit too much. I mean, what's the purpose? The only real reason I can think of of why you'd limit yourself to such an arbitrary shape is eliminating dead space for excessive air and drop usage. Which can easily be fixed in a lot of cases by no fly blockers.
I don't think the axiom of efficiently using space serves any real purpose and may have to be re-addressed.
