I participate in the Nday event with 300-500 puppets and want to share my thoughts from this perspective. Nday is a 24-hour event that I immensely enjoy, even though I typically play for only half of that time. I think the shield bank is a fantastic feature, but it could be improved by tracking shield donations and displaying them in the stats bar alongside interceptions and strikes. I suggest simplifying the system so that shield bank shields are automatically used when nukes would hit the faction it takes a shield from the bank rather than giving rands. Intelligence specialists could have the ability to bypass the shield bank, maintaining the need for active defense while giving the shield bank a clear purpose, reducing server load, and enhancing the role of intelligence specs.
A Nday API would be beneficial, particularly for faction commanders and puppet masters. It should include features like 'faction_member' shards to list nations within each faction with their specializations, and a tool to check individual nation specializations this could easily be wrapped into a discord bot to help give specific targets and orders for more strategic faction planning.
