I would personally prefer to play on the popular spider map. But with repeats, we'll never arrive at a single template, so I'm against it, and definitely not a diamond map, where the whole game depends on luck.

Regarding the size of the current tournament - didn't Den try a medium-sized map with a dungeon? If we don't take into account possible regenerations, isn't this still the best option in terms of neutrals and artifacts? There are also towers; without a dungeon, the entire map will be visible, and there will be few zones.
