No, but they dont have to say there going to do something then not do it..... rather they not say anything at all than empty promises.

A simple "Artifact Weapons will be delayed to unforseen circumstances, but updates will follow in the comming updates, and patch notes" Would of set a lot of people at ease. Post 2.0 they can hold back, "keep things secretive" to excite players, but til then I feel they should stick with the current trend of putting out info, and tossing "sorry delayed" signs out.
