I haven't seen this posted yet, sorry if it has. This is something I have been using for awhile now.
Download Netlimiter
NetLimiter - The Ultimate Bandwidth Shaper
Install it, and restart.
When you start it up, you should have a screen that looks something like this
Scroll down until you find WoW. When you do, click the + sign next to it, and expand it. You should have 3 different connections, 1119 is Bnet, 4000 is the one we are going to be slowing.
Under the "DL Limit" Column of port 4000, click the 5120, it should bring up this popup
Enter a low number, I use 50, and click enabled and hit save.
Your screen should look like this now
Now you are free to explore without fatigue and No Man's Land. All forms of chat should still work.
And no, you're not able to bypass the blue wall with this
When you're done exploring, just uncheck the box in the DL Limit column, and WoW will re-update your location to last known.![]()
