The developers are continuing their hotfix spree, this time targeting Replenishment in the arena. While in an arena, any class that procs Replenishment will only proc it for themselves. It does not apply to the entire party while in an arena. This is something that a lot of people have expected would happen eventually, and it's good to see that they didn't wait for another major content patch for something like this. It had to be done, so they did it.
