You folks excited? The troll instances are some of my favorites, partially from the flavor and partially because they're outdoors. Back in the day this meant that not only could I finally use Druid CC (Roots) but they felt so much less claustrophobic than other instances like Blackrock * or Auchindoun. ZG looks like some interesting changes and ZA's gonna be nice to do bear runs with my core guildies (small guild, getting more than 7-8 competent people on a raid night's still a mite difficult). Now we just need a glyph to turn the Druid bear form into the Amani Warbear. Ride-able, of course.
As for the mechanics changes, making valor points awarded for 7 randoms/week instead of 1/day's gonna be nice, make me feel a bit better for helping guildies do gear runs after the first one in a day. Guild challenges will help that too. Call to Arms probably won't see much use from me (I like my friends) but it should do more good than harm. Though I'm gonna get sick of dps giving me a hard time when they don't notice the other folks with the same guild name I'm tankin' for.
And of course ferals are getting nothin' but love this patch. Not a lot of it, but slightly better bear AoE, Savage Defense boost and Enrage becomes useful, while kitties double their swipe damage. I still laugh at the knuckleheads whining about the loss of threat modifiers without noting that the abilities get boosted damage to compensate.
The entire list of changes is rather long so I'll link it here instead of quoting the whole thing.
