Elo does not change on special maps today.
Suggest to replace it with the following rule:
- If map has proper horizontal/vertical/corner split and is not special elo changes as always.
- Remove special attribute from such maps as trololo/tiny skirmish, etc
While leave it on such maps as Kurzack(which is really very special).
- Optionally: introduce a limitation on small maps(4x4 and less), not more than N times/N minutes.
You always need skills to win small maps when they splited properly.
Thoughts, suggestions?
