A few things about the event, good and bad
Event building prizes not really worth the time, for me here and beta. Now, bcs things were screwed up in beta, I was able to get gold for 4K diamonds. We are given 1500 Ds for testing so really, it didn't cost me anything because I don't really spend it every event. In fact, I spend some every 3-4 events it seems. Here in live, I would never spend the D's bcs you really have to do a 160 board every day then see what is needed at the end, waaaaay too much hassle for me to even consider. And if in a race for gold at the end, it can cost a lot, each board is 2X ante.
Daily specials, if a QI player, really good, especially waiting for Koi ascended upgrades. We had every ascended upgrade for QI buildings plus the 2024 kit. If you are not a QI player, then not that special. depends on what you need.
Rivals isn't that bad, it seems they made it doable while you actually play, just takes a little patience. It was brutal the first round in beta, as mentioned, 6 quests each day and all over the place, usually 3-4 boards to complete. They went to Rivals every 2 days, I actually liked it and if flowed nicely so I am not surprised it went back to one day...lol If they make the quests doable, it is good to do for the extra gems and picks/prisms. The first Rivals live, with OR option we did not see in beta. If they are like that, not a big problem. One thing, I would have a goods building from your era ready, we saw them. You will need to do "finish goods" at times, I will keep mine at 8 hrs, ready to collect and see what happens. Colony folks have it different, just run 4 and 8 hour runs, 4 each and ANY goods quest will be a snap.
Diamond farmers, there is a good opportunity to get some well or shrinks. Talking to my diamond farmer buddy, he says get all quests done and you should have decent loot to get complete boards done. He said it can cost 500-600 energy to complete a board and there may be a few to skip until you get more gems. I guess you have to like the mini game too. I don't recall any events where a diamond farmer can get a building versus a few fragments.
EM and allies, since I do play the event, I figure the fragments will come so I have not really looked at it.
So, it is a 50/50 event, some will like and play, the others will not. For those playing, enjoy. And those not playing, you too, enjoy, your time away from an event.
