This is just theory I comes up with when I saw a thread says that you can queue bg for other peole. It's not verified but I posted it because I can't test it by myself so I want some people who're able to test it verify this for me.
I've read rules but I don't know anywhere else to post it.
As far as I know, when you invite someone into your group, WoW will treat that person as if he's in your group, it doesn't even care that the person you invited is already in a group or not.
This bug(?) already show some uses like allowed you to force people to help you ghetto heart, roll on other people screen, queue other people for BG
So I come to think that this may also work for the saved heroic instance or maybe even raid too.
Here's the method I came up with.
- After you done your heroic instance ( yes, you have raid ID saved )
- Run back out but leave at least 1 person inside the instance.
- Kick someone out of the group so that you have a slot for people to join your group
- When you saw someone going to enter the instance, invite him.
If the same mechanic as it did to roll/ghetto/queue bg applies ( which means it forced your target into your group ) and your timing is right, he should ended up in your empty instance, and yes, saved.
It's a bit difficult to test this because you need 2 people saved with same raid ID and one person without raid ID to test it, and it might not even work.
But if this works, you could make tons of people pissed off wondering why they can't enter the same instance as their group just by sitting there and invite anybody you see that is entering instance into your group.
