Hey CCP and all those Trolls, (as I know I;m going to get trolled by all those high sec griefing corps.)
The war dec mechanics are great by the way. Although there is one issue. There is no way to respond to a group of miners stealing ore in high from your Athanors. A group of multi boxes (possibly suspect botters) is free to mine your ore as much as they like. Unfortunately, there is no way to discourage this with the current game mechanics. While bumping is a thing it is hard for newer players to get in a good Battleship to support a fleet. You cannot war dec the corp that is stealing the ore as they most likely have no structures and you cannot shoot them without concord intervening.
So I propose a simple rule change (not sure how simple it is to code though). Use the access list for the structure to allow mining. While stealing the ore should still be possible, if not on the access list the offender should get a suspect flag.
Unfortunately this mechanic is currently allowing a number of smart ganking / griefing groups to exploit newer players in high sec and turn them away from the game.
