I think they should add PC crafting to citadel per PC put it somewhere around 240-250 hours and make it so there are scrolls letting you craft greater amounts of PC for a few less hours per one.
There should be stamina/energy potions for 1 PC ones that don't fill much like right now I am 50Tnl and I have 4 minutes till I have to go A small pot like that would be nice at times like these
It would be helpful to have a legion tab in crafting to know what legions you can and can't craft and what you need for them instead of searching for them
