Eternal world: For more than 6 years now hafen population would face the imminent decay after a few months. We have dropped from 650 online to 240. Meaning, that the majority of the server plays it as a sessional game already. The remaining folk are either waiting for something good to happen and/or gonna quit sooner or later anyways. That is the established user-behaviour that has been persistent for years. IMHO, the game design should be behaviouristic, rather than try to fight it.
Further observations have shown that the money income (token trades) are also decaying even now, when not so many people are speaking about the wipe being close. So, the token/subs are rather related to the interests of the people, rather than them being afraid of the resets. The token whales (people that would sell a lot of tokens) have quit/almost quit by now.
IMHO, hafen could benefit if the game would be rather sessional (4 months long as max) and you would be able to carry out to the next world some perks, like unique hats/branding irons with what you have accomplished last world and etc. Maybe some sub bonuses for certain achievements.
Updates: many updates done by the devs required further fixes and have caused a lot of unhappiness from the community. Consider discussing what you are going to work on with the community and see whether they'd find bugs/possible abuses. Otherwise, a lot of energy and time gonna go to the sink and that has been the case in the past. It rather feels like you guys are spending quite a lot of time on repairing the consequences of some updates.
The recent update is a perfect example: you have got to remove the curio stacking, the new walkable objects are making it impossible to catch someone and etc.
At least, the combat updates are worth of discussing with the majority.
