Who cares what anyone else says on this. You can do the mini quests in any order, depending on who you talk to and depending on what any of the Rhinostary people say to you. I advise you talk to them and compare what they say to each quest, then you can see which one you are to start on. After that, they kind of go in order on what the Taru's say to you. So compare everything they say to the quest summeries to find out which one you are to do next.
You have to finish Blue Ribbon blues no matter what so I do not understand why it is not on the list of quests. It is the last one and you have to do it too, so they might as well put it there.
Only after I completed all of the mini quests including blue ribbon blues, was I able to get the certificate.
And remember to zone after you complete either quest to get another one.
I think it is BS if you are not from Windy and to have this as a freebe for them on the new addon. We know how hard it is to get all those mages to the door. Windy has access to this from their missions. Thats the most bogus thing I have ever seen SE do.
