Why aren't we counting it as "something major"? What metric are we using as a measurement? Do we or do we not also factor in class balancing, adding dailies in other capital cities, etc.?
But this is World of Warcraft, not World of Jabbaprime. Some people wants to experience the lore only once; others strive for Achievements, or Gladiator titles, or cornering the market, or some other things. It's too bad that you don't like Firelands, but we shouldn't just use one person's standards when judging 4.2.for me personally I like to experience the boss and kill it, afterwards I don't really care much for doing it again. I did it, I killed Raggy, I saw the storyline/lore unfold, onto the next big baddy. Many people play for the experience and not the gj you killed him now kill him again with added gimmick for the next x months.
