War seasons based on fiefdoms are indeed the reason why war seasons are (sometimes) very unfair. You can win five fiefdoms during a season and just because you were ‘unsmart’ to do so, next season you could be punished just for winning.
You take the risk of being grouped together with teams way stronger than your team can handle. An example, team A has 30 fiefdoms and team B has 38 fiefdoms. Team A wins 5 fiefdoms and Team B loses three. Next season they could be matched against each other. Normally TeamB will have more and stronger members, unless players left the team. In normal situations Team A will stand no chance at all. Is that fair? Nope.
The current war map also is far from being ideal. Two alliances are located in the centre of the map and four at the border. There are a few scenarios. When a team in the centre is obvious the strongest, that team can cut the map in half. Remaining of the season will be very boring, they decide who is fortunate enough to get second or third place. When a team in the centre isn’t the strongest, they are in deep trouble. They can bet that first days of the wars they will have three/four wars simultaniously and even when they manage to win them all, they can be certain other teams still will go for them sooner or later, just because of the loser bonus that gives the teams in the corner the chance to beat them later.
That’s why I suggested another aproach, replace the war map by a competition with divisions instead. In division one the strongest alliance fight for big prices. There could be several divisions one to make sure teams not have to fight same alliances every new season. Work with promotion/demotion rules and after a few seasons teams will be in the division where they belong. When an alliance is growing and gets more members, they could promote. It has several advantages over this war season.
First of all, you will fight every team and not all at the same time. No more situations of teams having several fights at the same time, while others can relax and concentrate on one war. War doesn’t need to be declared, so you don’t need to stand up in the middle of the night (worst case) to declare a war, the match just starts automatically. Another advantage is that the skull loser bonus and skull reward are obsolete, no need for it any longer. And best is that the unfairness is decreasing. In theory you can be in the competition with teams that previously played two divisions higher, just because you promoted and they demoted and by letting them fight on day one, the team that promoted would have the advantage of war boosts.
But like I said, probably there is no one interested in a competition, due to the lack of responses in that topic where I suggested this.
