Before I start some whining of my own: congratulations ML on your fourth (mobile) birthday!
There are a few things about the Yntec Dungeons and Progressive Relics Island that bother me, however. In my view a birthday event is an ideal opportunity to create goodwill among the gaming community. Be generous and kind. Make everyone happy. Happy people are spending people. Not so much this time.
The Candles. They were hard to get for lvl 100+ players, because you hid some of them in a 72 hours challenge that is nearly unplayable for them. While lower level players could go several rounds without any problems, higher level players would struggle to get Muerte and Yndra and miss out on candles. This is not fair to the long time players who have helped shaping this game over the years, among whom many F2P who cannot afford to buy themselves into the event. Putting candles in Monsterwood was a good move, but without quite some luck there would still be missing candles.
Yntec needed to be crafted and hatched. In total this costs another 4 days, so approximately 100 gems to speed it up if you didn't get enough cells in time. That's a high entrance fee for a birthday party. Putting Yntec cells in Monsterwood is nice, but a little late. If you want to bother playing the relics event you don't want to start 2 days before the end, so speeding up required.
If this was a regular event, I would completely understand the mechanics behind all this: relics are valuable, so if you want a chance at getting them you need to invest time and gems. But this is a birthday event, and therefore everyone should feel a part of the party. Not feel frustrated because they are standing outside in the cold or have to pay to get in.
I think extending the relics progressive island with 2 days (so SP would chip in on the hatching and crafting time of Yntec) would create quite some goodwill again.
