Future of the game.
Lack of content.
Content coming won’t hold players to the game long.
New players come only to leave few weeks later.

1. Unknown, it's up to the developers to how long to keep this game in service

2.That is biased, Idiots who whine about this are blind to everything else besides "omgz hard core raids"

3. No amount of content holds people for long when they play for long periods, that's why companies have a hard time keeping up with the playerbase

4. happens all the time, people won't always like the games they rush to buy (<-what led 1.0 to ruin, buyers remorse)
