Before I start, I want to thank those that first found the warlock eye of kilrogg exploit, and whoever found out how to get out of IoC early.
Second, I'd like to say I've only done this on horde side.
Basically the idea is to use the warlock exploit on the back wall of the starting area.
If you use the port exploit to get out on any other wall you will just be ported back inside.
Step by step:
1. Enter Isle of Conquest and run to the back wall
2. Stand in front of it and cast Eye of Kilrogg
3. Toggle autorun and spam create port until you don't see it summon on top of you (it will be on the other side of the wall)
4. Cancel channeling Eye and use the port.
5. You're now outside before the game started and won't be ported back in.
Sorry in advance since this is sort of a repost, but it might give people some more ideas.
Edit: can provide screens when servers are up!
