As a wealthy player and a very long term player I have always dreamed about flying a capitalship in HS space. As their is fleets of tens of thousands of capitals floating around null space and MASSIVE ammounts of cash in both alliances and players hands I have thought of this as a solution.
Make capital ships enter highsec space by cynos or gates and make it as costly as possable.
Jump gates - 50m isk per gate
Cyno - 200m
100m every 20 mins of flight
Having these restrictions will make using a capital ship to defend/attack a citidel a hefty cost to the player and having it coming out of the players personal none corp setting means the player has a timer to act, removes the potential isk from mission running in the thing and lowers the chances of them afking on a gate camp.
These ships are as common as cruisers and cost less than a t2 battleship “marauders to carrier prices” and that to me is quite comical when you compair the stats…
Forgot to mention that if the pilot dosent have enough isk to cover the costs of the 100m every 20 mins of being undocked then concord removes his ship.
This is to me a very good way to remove massive amounts of isk and capitals which are as others have said very common.
