I tried your 1-15 method today but I couldn't get it to work. Now only having 5 accounts I had to use them for my boosters as well, so I got my level 1s all ported out to the temple. Then I booted one and pulled in my very well geared solo DK into the group and went in first with him. They lvl 1s tried to zone in soon after but they won't pass through the raid portal. I tried breaking and reforming the group using the DK as the person who created the group. I tried creating the group after the DK zoned in (and before he did). Nothing seems to let those lvl 1's get into the Ruby Sanctum. Is this something that maybe got hotfixed?

I was pretty sure you can't actually zone into any instance prior to level 10, raid or not.

The only thing I can think of is the team is one one side of a connected server (Skywall) and my main, the solo-DK is on the other side (Drak'Thul). Don't see why that should matter though, as it's a connected server not CRZ or something.

Only thing I didn't try was direct summoning them into the raid zone. I guess I'll try that next. Just wondering when the last time you tested this method?
