And without the industrialists to build the ships used by their attackers, they’d still be there too. What’s your point?
Isk provides no combat advantage. I could sink trillions of isk into an officer fit AT ship, the literal best of everything. And a player with more skill could probably take me out in a T1 hull.
Being able to buy the loyalty of other players through isk is not a combat advantage. CCP isn’t selling player loyalty.
