Hello, I have a problem with my latency, but it's not my internets fault. When i run speedtest it says that i have 2 or 1 ms of ping, when I run other online games I get steady 30-60ms ping which is normal, but when i play wow in warmane (deathwing) server I get latency from 200-1200ms. And it's impossible to play with this latency. My friend plays on my wi'fi too and he doesnt have latency problems. What should I do?
