I think I have to be clearer...

Related to the grid questions:

I have no problems with using a square grid to draw on.
I have a problem with a map constraining itself to those grids just for convenience.
I do not understand the need to use the square grid for the actual playing when there are inherent problems with using it and the mechanics have to be made complex to deal with them.

Related to the "always been done that way" discussion:

I do not understand the cognitive dissonance that people are willing to put up with for no apparent reason when it is so much easier to just make the change and move on.
