Zarhym says that it's just element of the mission's development

In reaction to a what I'd contact a troll on the group forums, Zarhym gives some cautious understanding to a issue that's been increasing its go more and more often as the encounter gets mature and older: products and success that once required time and/or expertise to acquire are becoming simpler than ever to get WOW Gold. Usually, when this subject comes up, we're referring to epics, but that's not always the situation. Here, the product in query is the Warlock set up. It used to need a long pursuit cycle to acquire, but after a sequence of choices on Blizzard's element, you can now practice it right away from the instructor as soon as you hit the required level.

Zarhym says that it's just element of the mission's development -- initially, the dreadsteed missions were element of the endgame, and just like the Seeker Rhok'delar missions, were developed to demonstrate that players had acquired the best of the category. But these days, level 60 isn't what it used to be, and the best way to do those missions is to have an advanced level personality tag along with you. That's not how Blizzard developed it (and it definitely doesn't fit within the "lore" of the quest), so they cast off it.

That questline is still in, just not required, but some questlines and benefits are obviously eliminated from the encounter absolutely -- their accomplishment no more symbolizes an comparative process, so Blizzard chooses to take them out. And that really seems the best way to do it -- though it's always a pity when contemporary players can't encounter the missions the same way expert players did returning in the day, the substitute would be to have them perform through material that is unnecessary, and no one wants that. As Zarhym says, there will always be new difficulties to take on.
