World-of-warcraft – How to reduce latency while playing World of Warcraft

I don't think money rates have been nerfed in general. Although, I think some mobs in various places (including Silithus) have been made non-elite, when they were formally elite, and as such, their drop values have probably been lowered. It does depend on which mobs you're referring to, and I think that, for the most part, things are the same.

Actually, there is. This is a general purpose latency fix, that can have a small to medium sized effect on your latency, depending on several factors.

It's known as the Leatrix Latency Fix.

It works by changing the packet buffer on your OS from 2 to 1. This increases traffic, but reduces latency by removing the wait time for confirmation calls under certain conditions.
