I just discovered something quite funny that I didnt know was possible.
I was bored and ran a few heroics before the reset
FIRST!: Requires a warlock in your group, keep in mind ;>
Now to exploit:
We killed the boss 5 mins before the reset and then we decided to try something to make this alittle funnier.
1. Like 1 min before reset our warlock summoned us to near the final boss.
2. Instances reset and we where ported to HS location.
3. The summon were still up and we accepted them, and BOM - we got teleported just infront of the final boss :>
Enjoy the happy farming - and hope you can use this exploit hehe.
