So I'm looking back on the first week of 6.2, and I must say that overall I'm enjoying the new content quite a bit. Blizzard seems to have found a good way to leverage some of the things they learned from Timeless Isle while really effectively encouraging people to group up to get things done.
In my first week, I managed to get my Saberstalkers rep to Revered, working with a couple of different groups over a few hours. I also managed to get my Vol'jin rep to Honored and I'm making some progress with the Order of the Awakened folks. They're clearly going to be the last to Revered.
So far I'm enjoying things in Tanaan Jungle. You seem to have several different options for things to do on any given day and it provides a nice catch up mechanism for alts, although at the moment, I'm preoccupied enough with getting it done on my main, that I have tried running any alts through yet. I'm not sure the content there would be as soloable with an undergeared alt, so there would be a lot more incentive to find a group in that case. Or you'd be looking at a sad dead mage.
On Shipyards, so far so good. I managed to upgrade mine to level 2 and am starting to work through the various legendary naval missions (or at least will be once the servers come back up).
I managed to blow through all the rares that I needed in Tanaan to get the various equipment blueprints in a fairly short period of time. I still need to do the Whale Shark, but there seem to be plenty of groups for that these days (although I need to get that done before those dry up).
So all told, the current impressions are positive. It is giving me plenty to do, and not something I'm quickly getting bored with. I'm anxious to try the first LFR wing of Hellfire Citadel once it is out today and see how that feels.
I've also done a little bit more leveling on my rogue. I'm anxious to get him to max level, because he's my last profession holder, and having level 3 profession buildings will make it a bit more efficient to knock that last one out. So he's sitting at level 95 and working his way through Talador.
