Played a lot of v3.02 today. I mean a lot. Good lawd.
First off, there was the problem of updating all of my mods. I wound up just scrapping the clusterfuck I had on there before (let's just say, I'd given Cosmos a try) and only put in the real essentials: Cartographer3, NotesUNeed, Omen (I don't use it for raids [yet], but it's proven to be a real life-saver for hunters and warlocks; and yes, I know Blizzard implemented visible threat displays in v3...Omen still does it better), QuestHelper, and, most importantly, Bejeweled. In 2.4.X I used LightHeaded/TomTom instead of QuestHelper/Cartographer and, frankly, I'm glad I made the switch. There are some things about QuestHelper that annoy me (namely, it being unwilling to directly let me set which quest I want to set the arrow to) but overall it's been a much better experience than trusting the commenters on WoWHead (not that the advice is bad, it's just that LH pulls in everything, even the outdated comments, so things can get confusing).
Stormrage was down for most of yesterday so I ended up rolling up a Blood Elf Warlock on another realm. Nailing lv.10 within three hours == very easy. I did so with plenty of dicking around between quests.
After Stormrage came back up I signed on as my hunter and played for even longer. For one thing, I love the free talent tree reset (I disliked some of the choices that I made early on -- my hunter being my first character and all -- and I didn't feel like paying to reroll). Pets having their own talent trees kicks ass.
Now I just need to raise a character to lv.55+ before WotLK comes out...
