This lag is insane. every time a group engages the boss on area 52 it lags the server for 10 minutes during and after.
Unfortunately your suggestion is gona fall on deaf ears here either use the ingame suggestion feature or either dungeon raids or scenarios forums or general.
Here is your answer; either enable War Mode (or disable it) or just accept it as the new normal around here.
Blizzard ignores the submit bug and submit suggestions.
They dont ignore just becuase they dont implement something that doesnt make sense doesnt mean its ingnored and not read dont spread misinformation.
