If you get 30 trinkets a day for the entire event, which is more than doable with the 4 quests that provide them (5 from Agnes' daily, 5 from the alchemy quest, and 20 minimum from the two pearl gala quests), you will be able to get almost all the new items. You're more likely to be getting 35-40+ trinkets a day, plus there's the special pearl gala quests that gives you extra trinkets; so if you're doing the dailies on the daily you should be not only able to get all the new items but a few of the old items as well. This event is actually incredibly friendly towards newbies/new players since the daily quests are the most efficient way to gather trinkets and the two daily pearl gala quests require no resources whatsoever and provide the most trinkets. The fact that you can't get EVERY item in one year if you include the older years even gives savvy newbies an opportunity to make extra potatoes if they want to sell some of the items instead, since there will still be demand for those items from players who want to complete their collections.
