@Icelander This is my point, what I mean is that there are different strategies in gaming both Powers as KGF, KJF, and so on in the case of Allies; Attack, defend and other options in the case of Axis; so a good gamer should have to know the game in full with all its possibilities, skills and strategies as well. I don’t think it’s superficial at all as you have to win in both sides. Some people just game one side and known it well feeling comfortable with that position but don’t do it in the other side, even knowing that TA system allows gaming and be skilled in any side.
I agree reducing time to obligate a most agile game and not to make it a turtle one and waiting for arbitration. As @Deltium said, double elimination allows gamers to a second chance.
About last paragraph, I don’t know if the following suggestion can be possible: instead of two brackets of winners and losers could be one of Axis and one of Allies with all participants gaming one side (different settings by aleatory seed) in both brackets as a single-elimination tournament each (regular bid 13 Allies, both side games should be done in 30 days), finalist and sub finalist of each bracket game (bidding) to the final championship and 2 other positions (could also be that both bracket winner is just one gamer and not need to challenge finals), so participants need to game one as Axis and one as Allies game, instead of double elimination and also it could make ToC quicker. It allows all participants to have 2 games and not to be out in just one. As mentioned, I don´t know if the system permits this way and how many participants can be in.
