@aristo In the response you said this was done. However that is not the case in game. They still share the same timer (21) and still causes the same issue. This seems a minor change that would allow zerks to be reasonably productive over longer raid fights without effecting group. Would still not even remotely put us on top of the DPS but would bring a closer gap to monks/rogues/mages on long raids and make us more relevent.
Copy of reponse in the question and answers forum: Q: Can you please move disconcerting to its own timer so that it does not share with mangling? Aristo: Already done.
