okay it isn't an "addon" per se..

Leatrix Latency Fix : WoWInterface Downloads : WoW Tools & Utilities

What does it do?

Leatrix Latency Fix will reduce your World of Warcraft latency significantly by increasing the frequency of TCP acknowledgements sent to the game server. For the technically minded, this is a script which will modify TCPAckFrequency.

You will also see reduced latency in other online games such as Aion, Warhammer and Lord of the Rings. The average reduction in latency (based on feedback from comments) is 66%. Click the Change Log tab above to see a summary of player feedback.

the fuck if i know what that means

found this tonight and tried it out. my ping dropped at least 50% on average, if not more. i can average around 80ms in dalaran at peak hours, wintergrasp i never broke 100ms over a 20 minute battle. i used to average 180-280, breaking 300ms occasionally on a normal day. definitely working for me and seemingly the majority of people who've tried it out in the comments but maybe it's just coincidence.

try it out d00ds

it has an option to revert the changes back to windows default if it doesn't work for you. i'm on windows 7 64bit and haven't had any problems yet. this shit rocks my tits

Or you can just add/change the reg key yourself without installing anything or going through all that trouble. This has been around forever.

you don't install anything. you run a .vbs script to install and another to revert the changes if you don't like it. it does the work for you and i'm all for that :shrug:
