I have been taking notice of the recent ideas that have been suggested by Devs since the Endgame Mechanic topic started being discussed and one thing that is standing out is the fact that you're trying to turn the game from PvP base to PvE base.
You are trying to shift the gameplay massively. In this move, you will have a large loss of player base.
That's a totally new concept you are pushing forward— to the old players who are still expecting that the old gameplay makes a comeback. From players' opinions on the forum, most of them want fun wars like in the past. The suggested draft does not move in the direction that the community desire.
I think the part of Supply Charge still needs a comment. It's a good move, I really like it. But will it not affect the revenue of the game? Supply Charge makes the game a subscription model type of business. It is the most bought item in the game while in war or not in war. I assume that those points are already considered for the upcoming changes.
A building should involve players only. Be it a Claim or a Travel Gate. Not bandit or random mobs. I will not wake up at 4 am to defend against some random bandits, but I will happily do so against other players.
The 4 hour time frame should help an attack as the defender must protect all of their buildings at the same time splitting their defenders around the buildings during that time. Leaving an building unprotected give the attacker advantage to claim the building. You can freely choose over 50 buildings you want to attack for an opening.
That is a severe miscalculation IMO unless I am missing some information.
Here's a given scenario.
It is always assumed that it will be Alliance against small clans. Let's pit 50 players for the alliance (understated number) and 20 players for the one clan (overstated number)
The attacks will happen at peak time, the clan will have a 4-hour attack window to take the towers.
There will always be 50 people to cover all 50 buildings. But not for the small clans. If the small clans concentrate their number in 1 specific building, the alliance will just follow up, and obliterate the clans.
In the end, resulting a harder battle to take over the tower. At best, the clans (attackers) will take only 1-2 towers. While the alliance will still control most of the buildings, whoever controls the building, control the Town Hall.
