Trinket change is now live.
"Nethaera
Summary:
We added a bit of cheating in the player’s favor to avoid long streaks of bad luck. This change is now live.
Longer explanation:
Traditionally, trinkets and similar proc effects in the game had high proc chances with an internal cooldown (ICD). This made the procs random in theory, but really pretty predictable. You would know that a trinket would proc on the pull and then reliably every 45 sec (or whatever the ICD was).
For 5.2, we made a change to trinkets to make them less predictable and less boring with the RPPM system. Sometimes you can get lucky and get several back to back procs. This feels cool. Sometimes you can also be unlucky, and get long streaks when the trinket just refuses to proc. A trinket that is intended to proc every 1 minute could in theory go 8 minutes or more without activating.
Last night we hotfixed in a change for trinkets that use the RPPM system. Every time your trinket fails to proc, it increases the chance it will proc. Unlucky streaks will be more rare and extremely unlucky streaks should never happen. In addition, we increased the chance for these trinkets to proc on the pull. To top it off, we increased the proc rates of the Agility and Strength trinkets in Throne of Thunder by 10% and the Intellect and Spirit trinkets by 5%."
