From the 1.8 notes

[Kordrann]

Latency upon entering crowded areas, such as Ironforge and Orgrimmar, should be substantially reduced.

Haven't patched yet, just wondering if this has been found to be true...

And if so, why in the name of all that is holy that Blizzard didn't advertise it a little better :confused:

My latency in IF was 250.. now im at 249.

Yay for less lag!

But for all seriousness i didnt notice a bit of a difference but not much.
