There's nothing quite so annoying then logging in, and getting killed while you are coming on the server. As a druid, I log out in Feral form, so that to hunters/druids I won't show on the mini map (amd stealth quickly on loggin in). As a mage with slowfall however, I like to log out on top of an inn, if possible. I still get my rested xp, but instead of being inside, I land on top. This is a great way to rest.
Here's what I do...
I find a mountain, climb to the highest, then turn on slowfall, and then jump down, aiming for the roof of the inn. Once I land on top, I find the spot where I "feel rested" then log out. When I log back in, even if the area is under attack, I can either sit and watch the festivities, help, or log out for another time.
