Scrap the reserve bank. Put more isk in the main bank. Then reduce the amount you get out the bank. Ie 1b isk in the bank if you rob it you get a half bil.
This will sort of prevent robbing your own bank and also give something worth actually robbing.
Imagine banks of billions being robbed.
Right now ess banks are 100 to 200m isk at most. Imagine if banks had like 1b-5b banks. Then peeps will have to defend it or lose it
Having all bank balances go to the 6min Main bank would favor zerg fleets. I think the current system is good, it allows bank robbery Ops to be countered because it takes awhile to rob the large balances.
The problem is they made some changes to the system recently that are keeping balances in the Reserve banks from building up in a meaningful way.
