This suggestion is geared towards the 'tier' function in events in which players have to work for a specific goal to open up newer items that increase in price and value.

It works in concept, but in practice many things happen that make the efficiency of the tier system doubtful in my mind:
-Different amounts of players are online each year, which causes significant work to be done by the admins each year to adjust the tiers. They would be able to save time and stress without this. Also, using this month's example: When adjusting Tier 1, many people shortly had access to Tier 3 and bought Angelic apps before Tier 3 was closed again. They had to be refunded and the apps wiped. Also, players would be much less angry at each other and the site admins this way- picture a mindset of 'can't wait for Tier 1 to open on the 5th!' instead of a mindset of 'Can you guys please hurry up?'.
-Especially in October, players a) don't explore in general, b) have better things to use their energy on than rabid animals (an outdated bar to measure), or c) aren't convinced their efforts are helping at all. Because of this, the tier bars travel too slowly, which is why Tier 1 is still closed as of now on the 11th. One year, in April, players never unlocked the Primordial Spring. This could all be avoided with a simpler, less stressful system that would save the site much work in the long run.

Since now storylines follow calendar dates, it makes the most sense for tiers to do so as well. This would also benefit August's Savage Studs, who should be able to fully cycle once or twice, and July's Celestial Raffle. Generally my pathway would be like this:
-Tier one: 5th or 6th
-Tier two: 14th or 15th
-Tier three: 20th to 24th (for enough buying, stud cycle, ETC time and to coincide with several event storylines finishing)

EDIT: It was pointed out October has four tiers. I'm not exactly sure how to deal with the events that have four tiers yet, but maybe a sorting of 5th, 10th, 15th, and 20-25th?

Each tier would simply have a guaranteed event calendar date to open.

Some might think that this takes away from Lioden's community experience, but I would actually nominate otherwise from what I've seen in main chat about the tiers being slow to open this month. Remember Tigon Hype? The community as a whole was actice, excited, and not under the stress to 'unlock' further tiger dad encounters. At a smaller but still significant rate people could just enjoy the wait rather than believe that we might not get Angelic at all this year. The community could treat Lioden events more like an activity than a job and the admins could enjoy never, ever having to watch the bar ever again.
