А вот как на другом сервере, где я играю (название офк не укажу)
- Proc chance now correctly scales with source, meaning you will have a higher chance to get a legendary in a Mythic+12 dungeon than in a Mythic+5, or higher chance from a heroic raid than from a normal raid, or higher chance from Emissary caches than from world rare elites, or etc, it depends on the complexity of the task.

- Anti-bad luck system: For those that don't know, this system takes care of unlucky players which farmed legendaries for a long time but were not lucky to get one. This is a rather complex algorithm, so there really isn't too much to explain here. We need to mention that there is no info about how it's handled on retail, it was just a result of our extensive research. The anti bad luck system is also dependent on the source (for example doing mythic dungeons increases the bad luck bonus more than a normal dungeon does, or more than killing rares in world does). Also, please remember that for the anti bad luck system to be effective, you need to actually farm them ingame, not stay AFK. Another important aspect is that the anti bad luck system will start being effective from NOW, so whatever you did until now won't count.
