Well, I came back from vacation and got 16 Demon Hunters to level 100. They're very fun (and fun to watch no less), but trying to determine how a class plays without talents is just too hard. Without Felblade they really have issues staying on a target, and they don't have a reliable snare.

Also, they removed Darkness from the Vengeance spec, which was a nontrivial part of the allure of Demon Hunters. Sigh.
