I am of the Brazilian gaming community , and we have some doubts about the new system.
Thank you for contacting us directly.
I am happy to answer any of your questions. There's a quick answer at the bottom for those of you who do not want to read a lot of text.
1.There is a fixed amount of Pokemons with high rarity that will be born?
It appears that many other people think this, but it is not correct. It is complicated to explain, but I will try to make it simple.
Spawns are not "limited" to time; there is not only one created every 5 or so hours. Instead, the system is built off of a simulation. We created a formula that looks for the average time it takes to find a Pokemon if many people look for it. That time range for the rarities is the amount of time that the
average person out of several hundred million simulated people will probably need to fight that Pokemon. The tiers tell you that we picked an hour within that range for the Pokemon to probably appear to you.
As an example, let us pretend that we set Pikachu to 7 hours. (Please note that is not the actual hour we picked for Pikachu, this is just for an explanation.)
In the simulation, a few million people might find Pikachu in 10 minutes. Another few million might see a Pikachu in an hour. Several million more see it after 3 hours of hunting. 700 million find pikachu in 6-8 hours. Another few million need 9 hours, a couple million need 11 hours. Maybe one person spends 30 hours and never finds one because he is really unlucky.
You noticed that most of the people only needed 6-8 hours to see Pikachu, but luck also plays a big factor. It also didn't matter that many of them were looking for Pikachu at the same time.
There is nothing that makes it easier or harder to encounter a rare Pokemon. You can find as many rares in an area as fast as your luck will allow you. You can find a Tier 5 Pokemon in 10 minutes and have somebody near you find another one soon after if you two are lucky!
If you are unlucky like me, it might take longer than expected too.
2. The shinys appearance was also changed with this new system spawns ? Or the odds remain the same ?
The odds are exactly as they have always been advertised. We have kept the odds true to 1/8192 (nonmembers) and 1/2048 (members).
The Shinys enter the spawns system, or continue to have a fee / opportunity / chance of appearance ? That is to say, it appears as respawns or I can find a shiny after another depending on my luck ?
It all depends on your luck. We just make some Pokemon harder or easier by changing a few numbers. But your luck can always overcome the system.
You should also know that the number of Pokemon on a map does not make things harder to find.
We changed the spawn system because the old one was was inconsistent, too vague, inaccurate and some of the Pokemon were causing problems because of where they were placed. For example, there was no reason to visit the old Kanto Safari because Splitting River Reserve had easy, free scythers. Cerulean Cave had easy, free Rhyhorns and HR Chanseys. We had to redo a lot of things to make the Kanto Safari worth paying to enter, and that meant changing a lot of other places. We realized the entire design philosophy behind almost the entirety was either flawed/causing problems or was not up to our standards, so we decided to redo everything.
tl;dr:
The actual mathematical/mechanical changes behind the system will not affect players very much. What
does affect you is how we
use the system, such as when we remove/relocate Pokemon or make a choice to increase or decrease their rarity. We are trying to make healthy spawn choices so that every area has a purpose. We also want to keep Hoenn/Sevii special and have the rest of the game spawns be in a healthy place for Hoenn/Sevii's release.
The system mostly benefits staff when they design spawns. We have a lot more accurate control over spawns and a better design philosophy when it comes to deciding where to put them and why. The changes were large in the back end, but all it did was make the system reliable enough to manipulate with accuracy. In the past, the actual rarities were mostly inaccurate guesses because the math behind the system was terrible.
