@Groshyr & @Lythrilux. I don't see why hostile bases would warrant demands or, as in the case of the Enclave in Dublin, roleplay notice. While the Core can probably value the cost of letting your enemies keep a base, I can't see house lawfuls letting their local crime syndicates and genuine hostiles pay tribute to keep their installation. The example you gave is admittedly a grey area that I can't clarify right now.
What I'd personally prefer aside, the code-monkeys that adjustments to the player base plugin are difficult. Rules adjustment is easier. Not inherently better, but easier to implement. We each have some thoughts about how best to handle this, but fixing the problem that is Maria player bases is tricky, and likely to be dramatic and controversial almost no matter what is chosen. Obviously I think my solutions are best though.
