Conquest of the Horde

So, recently i've been having trouble with a ridiculous amount of CoTH specific lag, to the point that I actually cannot RP because of frequent DCs. This lag is only around when it comes to CoTH, and I was wondering if anybody is currently experiencing this, implying it's a server thing, or if they have experienced it and know if there's a fix.

The only time I've really experienced unbearable lag is when in a raid that's spread out.

Honestly, it went away for no reason. So I don't know. How do I delete the thread?
