There are a LOT of complaints about this event. I would like to offer a different viewpoint.
I LOVE this event!!! Why? Because it overlapped with the last one - those that disliked the leaderboard - had something to do, and those who were working towards milestones, didn't have to do anything extra to earn masks!
This is the easiest, most laid back event, EVER! Instead of needing to be online all the time for hourly battles, 2.5 hourly collections, a variety of quests, this is more Set It and Forget It. To maximize masks, you only need to log on to harvest, (and replant) food - evert 5 hours for my Diamond Dates, but maybe every 20 hours for your crop. Am choosing all of my long evolution dragons - things that I can't afford to evolve during a Tale - Sunrise, Magic and Island duplicates (to trade) and Diamond hybrids - like my 40 hour Anubis. Means the chamber is churning nonstop - especially during the double mask portion of the event. I also bred another Anubis - which kept me from breeding anything else, so I popped water eggs on my two nests. So I need to hatch to hatch those every12 hours.
So instead of constantly being required to come online for battles, ridiculous collections, being required to spend apples for leveling something to a 15, needing to keep the nest and Evo Chamber open for requirements so I don't fall behind, this event is AWESOME!
Living the Dream! I am breeding what I want (well, trying to breed what I want), growing food, evolving my dragons that I can't normally evolve, and keeping my nests filled... I could hatch eggs from storage, but I need a place to put them.
I did hatch the blue and white ******y dragon from the Sleepy Slumberland event - nicely timed to move into the amazing 750 mask habitat which holds four dragons and 10K coins... now all three of the dragons from that event are hanging out in the proper habitat, and will get the extra Dreamweaver I hope to trade for a (?large?) pink gemstone...
Also, I think the estimates are low on the double mask duration. That lasts through the 13th and started on the 9th... four days of doubles. And after missing out on most of the double points in a previous event, I am trying to maximize the time on this event.
With my current strategy to log on as little as possible, I am currently have over 1400 points and will reach the third indy prize with my next harvest... that still leaves two more full days of double masks to work towards the final dragon - plus regular mask collection days.
Good luck everyone!
