The Mesmer Mental Anguish trait is not performing in WvW as it should after the recent patch.
Mental Anguish: Increased bonus damage to 25% base (50% vs. Inactive) in PvE only.
In WvW the trait has not been buffed and remains unchanged.
WvW is considered as PvE when making the distinction between PvP and PvE skills on other occasions.
Please investigate.
