That's repost from another site(sorry original poster, i dont know if forum rules accept links to external resources, so i better dont), just want to share it with u. Hope you like it.
how can a level 1 enter a dungeon for a level 85? I thought you needed to be a certain level to enter them.
This seems pretty ban worthy, especially since you would get an achievement for a cata dungeon at level 1. Might try it tho.
Theres been a bug if a group queues up for a random, then they invite someone else, they are instantly added to the queue without selecting a role. This has been used to get high level players into lower level instances so they can be power leveled. I never thought about bringing a low level into a higher level instance but I still think Blizz will smack the ban hammer down on folks.
U cant get into cata dungeon with a low level character. So u wont get achievment either. But you will recieve random dungeon reward, after completing the dungeon. That's 100k exp.
Leveled to 27 lvl in one hour. Post your actions step-by-step so you I can help you (if it is not hot fixed)
I queued for cata normal with 85 mage, then invited two level 35s, selected roles, and then it went away, and says "xxx must advance to a higher level"
Read the original post again, you need to queue as four 85's then invite one low level to it while queuing.
You should not queu alone. Invite another 81-85 level character, queue for instance, and when in queue invite low level characters.
i do it that way. Me 85 + 81 another + 2 low levels. I invite Pally and we queu both as DD. Than i invite one low level, he queu as DD. I kick 81 lvl, invite another one low level, he queu as DD. I invite 81 character, he queu as tank. Whooop instant invite and rando mhealer with us
