I wish it had everything to offer that the online server gets offered. It does get alot, but for example I did not see a vault section offline.
Our Offline Shop should offer everything and anything, because there's no reason it should not have even "pay to win items". That's not my cup of tea, but it does no other player any harm, "so why not?" To me, offline is the same as walking around your own house naked if you want to I do agree with @Littleoneloot02 , "all items should be made available including all heritage/Vault items". ~Time Lord Approves~!'
I have found that the founder, benefactor and telethon items as well as cotos can be purchased from NPCs in the offline mode. Which is really nice. What I love most of all about the offline mode is all the items I have purchased from the online store are available as well.
Really, they could just put all of the vault into in that one category. It'd get pretty long, but there is a search. If they add a batch, just patch it in the next month.
