In my opinion the problems with war deccing are too many groups use it as a system to flag people for pvp in trade hubs and nothing more. It’s too easy to avoid the war dec for people wishing to fight a war.
The first fix I propose is one that I think has likelihood of being implemented in some fashion.
Instead of charging isk for amount of pilots decc’d charge isk for amount of wars declared.
Make it double for each war starting at 50 million isk. The price for war is the same across all wars. If you have two groups decc’d its a weekly fee of 100 million per group. 3 groups decced is 200 million per group.
Secondly people who quit corporation during a war should remain flagged as a war target during the duration of the war.
If my structureless group is trying to push another structureless group off of an ice belt in a system I should be able to do that without them all going to NPC corps and continuing to mine the ice belt.
Charge players who leave corp a weekly fee for not being flagged a war target. Balance this fee in some way, double their skill points maybe.
Allow us to wardec single players in NPC corporations. This way I can push off that orca in the ice belt i’m attempting to take control of. Allow them the weekly fee for not being flagged.
All fee’s paid should go to the opposing group.
