Well, with my limited playing time, I dinged 80 last night in Sholazar Basin. It is a pretty fun zone that is basically a remake of Ungorro minus the annoying patrolling elites. I ended up spending a crap ton of money leveling my engineering, but I did obtain my Titanium Goggles. My engineering is now 441. It seemed like almost every node I flew by in Sholazar had someone on it. I even saw players as low as level 71 out ther mining...WTF?
I did some equipment swapping, and I am now at 520 defense. Still 20 away from the magic uncrittable number, but I havent even got any defense enchants on my gear, so hopefully that will cover it. After I finish my last quests in Sholazar, Im going to head to Zul'Drak and start doing the questing there. I am very excited about "championing" for rep and cant wait to run all of the 80 instances and Heroics. If everything goes well, I plan on running our first Naxx 10 man next Saturday.
