Vip.rus, regarding the ranking: in the league, the ranking is based on the results of the last three major tournaments (with the most recent tournament having the greatest impact on the ranking), so this ranking can be considered quite objective. As for the draw: I also think it's flawed, but since I'm not an organizer, I'm wisely staying out of it – if you want to be in the top 3, you'll have to beat the strongest players along the way.
Regarding the mod: in all versions of 5.0*, there are some bugs (for example, with the starting army of heroes), so it is not recommended to play them yet. Since there are 10 days left for the game (plus I think the organizers will add another 2-3 days, totaling 100%), I strongly recommend waiting if you want to play on 5.0*. I personally will be waiting. As the creator and coordinator of the development team, I want to assure you that the update will be released as soon as possible. Thanks to the test games, I hope that most of the critical bugs have been identified and fixed.
