When i first discovered this it came across as kind of common knowledge but from my searches i've yet to find a post on MMOwned about it, it's pretty much a macro that you spam for about 10s and it lags out your game, it D/c you but it doesn't actually kick you out of the game for 2-5m, hence giving you free exploring time. Works in both instances and in the world.
It's simple, make a macro and type the following into it, each on a seperate line:
/w "YOURNAME" Rofl
/w "YOURNAME" Rofl
/w "YOURNAME" Rofl
/w "YOURNAME" Rofl
Continue copy and pasting untill it's completely full, but if you end up an incomplete sentance at the end, delete that last sentance, then put this macro into your Action Bar 1 slot.
After that, create a second macro with the following:
/click ActionButton1
/click ActionButton1
/click ActionButton1
/click ActionButton1
/click ActionButton1
Apply the same rules as the first Macro.
After you have completed that, drag the Second macro to any free bar slot, and spam it for around 10s. Congratulations, you now have a few minutes of non agroable mob exploration. My guild isn't quite up to BT yet, so i had some fun with this in there, but as i stated, it works anywhere, allowing you to walk through instance portals etc.
Enjoy =)
