Since there is a lot of people asking for a Burning Legion expansion again (and seems that it is almos offciial that we are going to get one at last) Blizzard is taking a lot of risks, even more than doing something totally new
For example, when Blizzard announced MOP , something totally new, there was a nerdrage but at the end ,since nobody exactly knows what to expected, it ended to be a very enjoyable expansion
Now that Burning Legion is returning, what would happen if Blizzard deliver it and it has nothing to do with most fans expected or decired, or if is not what they envicioned during all those years waiting for the return of the Legion? The rageee is going to be WORSE than with MOP
