The power of /ins
I think this little command is highly overlooked. The normal use for it is to get into the same area as your group.
You have a normal recall that takes you back to your recall point, but this is on a timer and can only be used occasionally. Instead, use /instanceselect.
Some times to use it:
When you're about to die. There is no cast timer or wait time. It's instant!
When you want to get out of an area and not fight your way out.
When you want to go afk, this is a safe spot.
PVP Escape
For now there are no limitations on this command. I can see them eventually putting a cast time on it... somehow nerfing it.
