it was stated before expansion release the ETA on when we should be expecting new tomes and raid etc. this was to give players who wanted a chance to experience and appreciate the game the opportunity to do so with out feeling they were a week behind on tome capping/raid loot. this hold on the release of content was given to the community as a courtesy.
some people may have been playing since expansion release and may not have a 60 yet or focused on crafting or whatever. maybe they will feel this "rush" too or as though they are falling behind. but not everyone works at the same pace. to with hold this already expected content would put a wall up on those who do progress at a faster pace.
or what about raiders? people who pretty much only play for the more hard core of mechanic content? should they still have to wait for the game they love? if not, theres the other side of the player base who wouldnt find it fair to not have equivalent ilvl gear to be able to obtain outside of raid content.
everyone has a pace. the game can not cater to everyone or any individual but they try.
dont fret, get upset or worked up about it. just continue at YOUR pace and play the game you like
