Workshops should be given to all players. Remove them from Free Companies and place them in the Grand Company Barracks where your Adventure Squad is located. Place a minimum rank requirement to unlock the Workshop, maybe 2nd Lt.

Get rid of the requirement to have 4 people partied and in the room. It serves no purpose when the people involved don't even have to be part of your FC.

Place Fuel Tanks in the GC Quartermaster list so you can buy them with Grand Company Seals. Keep the fuel tanks available for FCs to purchase with FC points, this gives FCs with spare points some advantage over individuals.

These changes impact the game in many positive ways.

1) gives all people access to airships and schematics if they want to play around with them.

2) gets rid of all the FC Workshop shells taking up housing. There is no need to keep all those houses for Workshops when Workshops are now located in your Grand Company Barracks.

3) with the GC rank requirement to unlock Workshops, all those level 1 mules currently running FC Workshops will become useless.

Keeping the Workshops in Apartments only moves these mules to Apartments which helps but then Apartments may end up in the same situation as houses.
