How often these days have they 'met their stated mark'. Sadly, rarely, and then drop some random content on us anyway.
It's interesting to note that FC implies crafting is implicitly tied in to the raid. I was merely contemplating a method whereby they could break off the first and maybe second bosses to cut our teeth on for a while which gives them time to work on more bosses and crafting thereafter. Traditionally, this would be easy, because the first few bosses in the T2 and T3 raids had nothing to do with crafting, but maybe this new dungeon has you progressing through all of them in a way creating ingrediants for final boss. This is all just me speculating, and just wishful thinking.
