I'm experiencing lag spikes on only one character. It seems to happen every 5 to 10 minutes, in instances and the open world. Everything will freeze except me, i'll get receiving:0 on the upper right corner, then after 5-20 secs (it depends), everything fast forward and then back to normal.
I don't know what causes this as it's only one character, the other one I play with is fine, never any lag, and both characters are on the same server.
