I watched part of the livestream and I have a suggestion on how to improve claims so large companies have a reason to use the neutral setting (let other people build in their claims).
Currently it is not in the interest of companies to let others build because 1. they can just avoid taxes 2. people are paranoid 3. the 'guests' can start stealing the territory (or at least there's the fear of it happening).
What I propose is to implement certain bonuses to claims. Attacking a member or an ally of the owning tribe would suspend the bonus for a long while, the bonuses could also be company specific. The bonus would be provided by a certain building. It could encompas many stat bonuses, but the main one I believe would interest people is bonus resources. Proivided the bonus is big enough (there could be tiering), the guests would not lose as much (due to taxing) or even gain more resources (if the bonus is greater than the tax).
The owners would benefit because they would get more resources, while the guests would gain more resources and feel less opressed by taxes and therefore less likely to try to claim the land for their own.
Bonuses could possibly also apply to members/allies of the owning tribe, so they have motivation to protect territory and similar. If it is not done, however, it would incentivise guests because guests get the bonus and therefore get more resources (altho the owners only get the tax).
Any thoughts and oppinions are appreciated (I'm sure devs like different oppinions on the same topic to gain insight into what the general comunity is interested in).
TL;DR: Give bonuses to claim guests to make neutral claims viable.
