I agree. Vash'jir wasn't popular but I actually found it to be one of the most interesting places in WoW. In general zones with heavy phasing tend to be more miss than hit (Icecrown is another rough zone) in the repack, though I empathize as they probably aren't easy to get working.
Apologies...
Chain dead ends pretty quickly at 'On our own terms' #25547 where Taylor cannot be interacted with (probably wrong phase).
Searching "on our own terms" on these forums is a fairly fruitless exercise too. :-/
