Will they still get realm first achievements?
Not that it should concern me, as I won't be leveling a monk the first week of the new expansion; however, based on the feeback of someone in my guild who will
be leveling a monk the night of release, and my own thoughts as well, I don't see how it is fair to let those Monk who leveled through the RaF system to be eligible for the realm first feat of strength.
There is no reason why RaF shouldn't work for Monks, I think that is a breath of fresh air for those who wanted to reroll at the start of the expansion to have that option available to them, especially if their time is limited.
However, the realm first feat of strength should be something you've earned, and certainly not something that should put those at a disadvantage that are willing to work hard for it. Death Knights who chose to level through the RaF system were not eligible for the server first feat of strength at the launch of Wrath of the Lich King.
This confirmation kind of makes it seem as though Blizzard is comfortable with people manipulating the RaF process for reasons other than what it was intended for.
