Maybe not to you, but when Blizzard is calling them "Dark Ranger" it means a great deal.
Demon Hunters and Evokers kind of put the nail in the coffin of 4th specs. If Blizzard can't be bothered to create new classes with 3 specs, they're certainly not going to give multiple classes 4th specs.I answered all your statements with Red but this leads to one of 2 things potentially happening, 1) We will see 4th specs appear later on or 2) With the new talent system in DF maybe Dark Ranger skills will be made available through talents and hopefully kept competitive with other spec talents.
