Dragonswrath was initially intended to be obtained only by people who had cleared all previous Tier 11 normal mode content. However, as less than 40% of total world guilds have been able to do so at present, Blizzard changed the design to instead require killing a "mini boss" in Firelands to start your quest chain.
The end of the chain to actually obtain the legendary still seems to remain unchanged as of now, so the fact remains that in order to officially gain the legendary staff itself you must be able to defeat Ragnaros.
So, with that all being said, do you think that the quest's starter portion should have been changed or remained the same as it's initial design? Please don't turn this into a "casuals don't deserve legendaries" thread, this is NOT the question that is being presented to you.
