The title of this article is completely mis-leading.
I fail to see how dropping 4 classes out of 24, and some of the capital city sieges, is 'Massive'. Massive typically means a very large quantity of something.
In terms of the game, while these delayed items will be missed, it is a small percentage of the overall game content.
At least read the interview to understanding what was actually announced and the reasons behind dropping a few classes.
