first I thought it was my internet I measured my internet and it was all perfect even before entering a mythic or raid or bg I am latency (world) in 150/200 as maximum goes perfect but when entering the mythic triggers and tried to talk to the active gm and told me to deactivate the addons but everything was the same told me that nothing has ever happened like this.
and I intend to erase cache and using only my concentration to the internet and even then it goes down and deactivated the sound addons and even then it does not improve, I use 10 megabytes of internet for 1 year I've been on the server for 4 or 3 months playing and I did not Nothing like that had happened. to other members of the brotherhood in which I find myself saying that it happens the same every time you try to do a mythic you raise the latency.
