What we need:
We need a healer and tank for sure, and possibly a dps.
PATIENCE PATIENCE PATIENCE, and just incase you didn't get that the first 3 times...PATIENCE.
You need to be willing to spend the time and camp these until they spawn.
There are also other groups that farm these (especially alliance), which means there will be times when they come up and kill us while we're killing the rare. When this happens you need to either A) Be badass enough to kill them while killing the warbringer or, B) keep running back after you die to keep the tag.
One last things, it would be nice if people that join the group are willing to stay for a while after they get a mount instead of bailing right away:)
If you think you can do these things and want to have a chance at mounts then hit me up in this thread or in game boots#1708.
