The Frequency of Invasions needs to be modified from once every 4 days to once every 7 days! Most servers are not capable of reliably defending from invasions, especially as more and more players AND every lost invasion results in towns being downgraded, and recovering from those downgrades is even more impossible for a variety of reasons:
1.) Population decrease means that there are less people able to participate in defending from Invasions. Many invasions even struggle to field 50 players - combined with the inability to assign more than 10 players to groups, losses are inevitable.
2.) Population decrease means that there are less people logged in to complete Town Board missions to re-upgrade crafting stations.
3.) The lack of new player population means there is a smaller and smaller population of players that get any real incentive to complete Town Board missions to re-upgrade crafting stations.
Please, please, PLEASE consider reducing the frequency of invasions AND/OR reducing the penalty applied to town crafting and refining stations when losing an invasion.
While I agree that low pop servers need a different configuration for invasions, the actual solution for this is server merges. On high pop servers the more invasions the better, since more people will have the opportunity to join and play them.
In addition to the population decline, the inability to select your full war board severely hinders the defenders to even complete these already relatively difficult instances and prevent the downgrades.
Consider how bad the concur players are at right now…and fact that barely anyone is leveling like the first 6 weeks of the game…maybe once every 2 weeks for invasion is more like it.
