We have added some protections for unlucky streaks for trinkets that use the RPPM (real procs per minute) system. This change is now live.
In general, trinkets and other proc items in games have a relative high chance to proc, and they have ICDs. Theoretically, the proc change is random, but predictable. You may know that one trinket will proc randomly at first, and then proc every 45 second(or proc at other ICDs).
In 5.2, we are using RPPM system to make the proc mechanic more unpredictable and not that boring. When you are lucky enough, your trinket may proc in a row, which makes you feel great. But on the contrary, sometimes it doesnt proc at any rate.
We have made a hotfix to this RPPM system yesterday evening. Every time the trinket fails to activate, there's an increasing chance that it will activate. The time you are unlucky will be less, the time you are super unlucky will not happen. Furthermore, we have increased proc chance for these trinkets. In general, proc chance for agility and strength trinkets from Throne of Thunder has been increased by 10% and proc chance for intellect and spirit trinkets from Throne of Thunder has been increased by 5%.
Painful Theory Explanation:
As usual, if you want to use these trinkets, or you want to know how to use them better, you don't need to read the explanation below. The explanation below are for theorycrafts and geeks to understand the details of this system to design different kinds of character models and simulators.
The calculation of proc chance remains unchanged, and you can figure out the average proc interval. We are now tracking "the time since the last successful proc". This "time" is different from "the time since the last chance to proc". The maximum value of it is 1000 seconds.
Proc Chance = Normal Proc Chance * MAX(1, 1+((the time since the last successful proc/average proc interval) - 1.5) * 3)
For example, if the average proc interval of a trinket is 45 seconds, and the time since the last successful proc is 72 seconds, then you will get 1.5 times as much as the normal proc chance. If you are out of combat for a period of time, and the time since the last successful proc is 5 minutes, then you will get 16.5 times as much as the normal proc chance.
