The ingame script for anti-spam is causing issues for me when i do callouts in Arathi-basin. as i'm only available to do a few ones before i get a 1 min mute.
Under this 1 minute we had alliances attacking 3 bases where we lost 2 of them, just because of the anti-spam script.
This causes more troubles than helping, i do believe that it is not needed in battlegrounds, and if someone were to spam you could easily ignore them
