I've already tried to create something similar; the topic is called: Rules for Offline Tournaments + FAQ
Take a look; maybe after reading it, you'll have some comments and suggestions...
By the way, if such comments do appear, please send them to me via PM or write in the thread TOURNAMENT MATTERS!, but PLEASE don't go off-topic in this thread because it is dedicated to a specific tournament.
Sincerely.
Personally, I disagree with point:
1.4.10. It is forbidden to weaken unupgraded neutral armies through repeated defeats.
Although I'm not particularly against it :)
It simply artificially prohibits a perfectly definite tactic for completing battles. That is, you can apply this tactic to non-mixed troops, but not to mixed ones.
