Total gold earned (most of it from selling materials on the auction house) - in the general region of about 14,500. Both professions (mining and herbalism) are above 500, well before Tal's hit any areas where he'd need to have his skills that high level to gather herbs or ore. Nice!
When Tal dinged 80, his average iLevel was about 161. The first Cataclysm mobs he had to deal with felt like they were somewhere in between a tough Wrath mob and a weak Wrath elite mob. I could take on one fairly easily, two if I was able to plop down totems and blow through cooldowns.
By the time he hit 81, the quest rewards from Mount Hyjal had pushed his average iLevel to 238. The only items of his that I haven't been able to replace with Cataclysm gear are his trinkets and his belt. Quest mobs were still on the somewhat tough side, but with totems down and cooldowns ready, they went down readily enough. Handling 3-4 at a time was a challenge instead of a death sentence.
Attack power? Went from the vicinity of ~1380 to 3153. Yowza.
Off to finish Hyjal now...
