Didn't see this thread before!
Loving the expansion. It's actually more fun than I thought it'd be. Even though we were in the beta, we didn't level up our characters because we didn't want to ruin the experience (and be basically doing the same thing all over again). My husband's avoiding rest state so we can really take our time getting to 70. After being at 60 for several years, it gets old being at the top. It's really nice to watch the progress again and we're doing all the quests in each zone and we'd like to complete them while they're yellow, not green, hence avoiding rest state.
We seriously spent all of our time raising engineering first instead of focusing on quests. We're stuck at 360 now because of lack of recipes (mostly dropped at this point), but we've both got our goblin/gnome transporters and are sporting spifty goggles. I loved, loved, loved DEing all my Molten Snore gear. I couldn't wait to dump that crap. Spending months raiding the same zone over and over? Glad to see that gear go. I did have to listen to a few people whine about all the time they put into BWL only to have it replaced so quickly. Wha? They want to be buried in that gear? Go right ahead. I don't want to hear about it anymore. My favorite part of leveling was all the new clothes I'd get. It's been a long time since I've run around in pants and my husband said it was good to see me not wearing a dress for a change. Nice upgrades drop in dungeons and I'm not even rolling against my friends because that stuff will be replaced in a level or two anyway. I'll worry about that at level 70 and all!
I just like wearing gear that no one really knows where it's from unless they've done the quest themselves or have the same item from a dungeon. I was so tired of people being visibly measured by what dungeon gear they were wearing (Naxx, BWL, and MC) and how everyone was starting to look the same in the end. I even did PvP two years ago to get away from it and for a long time, I was the only dwarf priest wearing the pvp gear. In the past year, saw dwarf priest alts wearing 'em. Just wasn't different anymore, y'know? The ride to 70 again is a real breather. I know we'll hit 70 again and settle into new routines of trying to look different by doing harder dungeons, blah blah blah. At least I don't have to deal with that again for a while.
