Go to this thread and start hoesntly spamming your grievances, there is no other way at this point, the time for civil discussion is over, they wont listen to normal feedback.
Make more ruckus than we did on 1st QA, they wont listen any other way, they will just keep spending all their time on mage changes because its Celestalons main and neglect warlock because noone in the dev team plays them anymore. So spam to your hearth content, because at this point, any rational discussion is futile. Air any and all grievances about current design, and keep doing so. MAKE THEM LISTEN even if they keep sticking their fingers in their ears and chanting lalalala.
