The one good thing about Legion verses WoD, is I have not had beta access, so I have no idea how bad or good it really is or how much of the story or content will actually be scrapped this time. The way they gutted WoD, was shameful and it really screw up the overall story and theme of the expansion. I was not at all impressed. I have also learned over the years to not buy the hype and just play the game. If I actually bought into the hype, I would of quit the game many years ago.
Legion is just another expansion in a almost 12 year old game, its shelf life is only as good as the content they continue to put out. I know one thing, the content patches this time around better actually have content in them and not just slap something in to fill in the gaps for one big patch at the end. I truly wonder if they actually learned their lessons from what they did with WoD? I guess will see if they did in little more than a month.
