Why only one map? Is the regulation already ready? ;)
I suggested a method for selecting maps. If we choose one map from a group of five, we will miss out on many good ones. It would be more beneficial to first create a large pool of maps, which will be screened by a committee, and then use an automatic draw.
In general, I agree with your list, Dim... Except for Showdown:D Sorry, I don't have a good feeling about it... :( but that's just my opinion.
