I think this is way to long, tbh if someone has not logged in after 30 days they are not going to log back in. Land for tribes is everything in this game, if we are to support a healthy population tribe totems abandonment phase is going to have to be much shorter than 4 months.
In Darkfall you can lose your city within 24 hours if you are not there to defend it for a siege and player housing has 13 days total if you haven't paid your taxes by then you lose it.
I know this isn't Darkfall, but when you are talking about territory control and the need for real estate to house players land is everything. In darkfall they don't have to house every player because they have NPC cities to do that for the ones not lucky enough to get a house or those that don't live in clan cities. Every player that comes into Xsyon has to be "housed" within a territory either controlled by many or by just 1. 4 months may seem fine right now with the population so low and so few people putting totems down, but when this game has lots of people coming in it's just going to get really crowded again with unused totems taking up the majority of the space.
