But as far as the way the game operates, I was most interested in the worgen racial skills:
BlizzCon 2009: Live blogging the Cataclysm new starter zones:
Two Forms, instant, 1.5 sec cooldown, Turn into your currently inactive form.
Darkflight, instant, 3 min cooldown, activates your true form increasing movement speed by 70% for 10 sec
Viciousness, passive, increases all damage done by 1%.
Flayer, passive, skinning skill increased by 15 and allows you to skin faster.
This is a druid's dream slate of racials. With the elf, I get shadowmeld, which is nice, and was much nicer when I could eat and drink invisibly while mostly soloing my way up to 70. The tauren's stomp is useful, though perhaps more in PvP.
The worgen get dps, the ability to, I assume, cheetah away indoors twice per cooldown (once with cat form, another with racial), and I'm as envious as I could be about the faster skinning and built-in Finkle's Skinner and a half. Lissanna adds that they'll be able to use their claws to skin. Even more useful than the Gnomish Army Knife Jal's carrying. Seriously, how often do I cook on the road? (For those out of the know, the army knife includes a firestarter as well as a skinning knife, "Gyromatic Micro-Adjuster, Arclight Spanner, Blacksmithing Hammer, and Mining Pick", and takes up one more space in your pack than wogen claws.)
So so far, so good on the cataclysm. Interesting Old World reuse, a new, interesting druid race, and what appears to be an honest attempt to expand lore, rather than tack onto it. I'm looking forward to CC more than I was to BC and LK. I wonder if my nvidia Mac mini will still be up to the task.
