Since I waited a lot for the answer then here's a question: if I were to add a page for Armello shippings do I have to wait until the game becomes well known/popular?
Not at all. You can add any ship at any time, as long as it falls under the wiki's rules. No fanon-incest ships and to ensure that the page stays up, correctly contribute to the page. You and your ship pages will be golden. :)
I have the info ready since three weeks ago but I just have to write the plot and keeping the the page up to date might not be easy, oh yes most of Armello shipping names are from me since no one ever give names for Armello shippings
