How to get away from the Garrison in WoD?
The trick is to run very fast in an opposite direction from the Garrison. You will notice a lot of players lagging there.
Just run away to a different area (from the same zone).
What usually happens is that you will be able to run but not be able to use any abilities. Most likely you will be thrown back to the garrison area where it lags.
Just repeat all this running for 2-3 times and you will get disconnected at some point.
Log back in and you will now be located in the area that you reached when running away from the Garrison. Don’t go back there until your guildies will say that the lag issue is fixed.
