well today while completing a few things on my soon to be 49 twink i encountered a bug. I am more then positive this was not an intention, but as i attempted to run out of zul'farak i couldn't leave the instance.
I was riding on my buddies mammoth and as he left the instance portal i got dismounted off his mammoth with about 30 mobs following me. this ofcourse was shitty so i attempted to flee out of the portal. However, for some reason i was not aloud to just zone out. i instead went through the instance portal and was not stopped but the invisible wall that normally accompany's not being able to zone out of an instance *for instance having heroic mode on or what have you*. I have jumped out of zul'farak to explore unintanced kalimdor before and this was just that.
NOW this might not be incredibly useful or even gay for zul'farak. However i feel that any instance that you have the ability to mount in will give you this opportunity.
I have yet to try other instances as this just happend and i figured it would be a good share.
feel free to try it out and post what instances you got out of and explored.
*this also makes me happy because, after the nerf to wall jumping you could no longer explore uninstanced places you previously enjoyed, so having this happen was quite a fun thing*.
have yet to check if existing posts on the subject exist. bash away.
