Hey.
So, I searched but I did not find any similar trick (my apologies if one already exists). I do not know if it truly is an exploit, but it can be really useful. That's what I used to farm the Baron Rivendare's mount.
As you know, finish the instance take 6 minutes. However, the reverse path to the resort can take 1 or 2 minutes. My method allows you to instantly go out.
This is simple, you just need a friend or guild member who is questing (for example) and does not need to be in a party.
Invite him in your party, rush the Stratholme instance, and just before killing Ramstein the Gorger (in the last room), leave the party. You have now 1 minute to kill Ramstein, the wave of undead, some trash and Baron Rivendare. You will have 10 seconds to loot him. After, you will be teleport at the entrence of Stratholme, ready for a fast new rush. Repeat and profit!
Note:
- Be sure that your inventory is not full so as not to waste time and panic if the mount drops.
- You can invite your friend at any time: before going into the instance or just before the boss. Stay in the party one second before leaving work perfectly.
- You can also make such a macro to save time:
/invite {player}
/script LeaveParty()
