It took 8 months from the previous patch to release (btw, i'll be calling 6.2 6.1 in this post, because that's what it is)
6.1 came with a zone that was supposed to come at launch, and the zone's content became completely worthless less than a month if you played more than 45 minutes a day. 6.1's reputations were better than 6.0's, but the sheer lack of narrative and purpose made the dailies feel like a chore, and the rewards were lackluster. The rares were easy to kill, the zone rained loot, making gearing from it irrelevant quickly, and world mount rewards were simply the rejected recolors from 6.0. The raid doesn't have anything jarringly wrong about it, other than some class balance, which every patch has issues with. The shipyard felt like a last-minute usage of some nautical-themed art assets, that were probably made for 6.2 (which never released), and honestly felt like it dragged players along, hopefully keeping them busy over time. 6.1 will not last for the 8-ish months until the release of 7.0.
