What day and time does the guild rep cap reset? I play on the US Wildhammer, a central time zone, realm. However, please answer this question so that it helps anyone from another realm.
It resets (for most characters) at the same time as the raid resets, etc, which tends to be 3 AM Tuesday morning for the U.S. or Tuesday night for Oceania. However I've heard reports that it varies for some characters, and they may reset at 3 AM Monday mornings (U.S. time) or other times during the week. However I haven't experienced that myself.
