@Kyronix dunno if this is working as designed... and it will probably make
@Silent Singer pull some hair out...
but...
I had completed the entire quest chain on a char.. went back later to do it again.. had to redo the whole chain.. but when I went to fight the Myrmidex in the pits others had already ran them all the way back to the furthest area. I was able to get in one flamestrike on a redlined Shaman.. and got credit for pushing them all the way back and was able to advance in the quest chain to the next parts...
