Gear is static: still sporting the augmented chain armor, as I will for another 7 1/2 levels. Bleah. On the plus side, I seem to be doing a decent job of tanking - I'm think I've mastered "Keeping Aggro (101)", and graduated to "Regaining Aggro When The Mage Starts Setting Things On Fire (102)". I'm still a pretty horrible fail at using Righteous Defense, though. I really need to find a decent macro for it, so I can make it part of Aeven's tanking repertoire instead of an "Oh, yeah - I could have used RD there... crud" ability.
In terms of talents, I've been putting points into the protection tree for the last dozen levels or so. I think that when Aeven hits level 40, I'll go ahead and pay for a respec and re-allocate her talent points to be a more solid prot spect instead of a prot/ret hybrid. Or... Hmm. I've got a bunch of materials I've been stockpiling, thanks to mining and skinning, with an eye towards power leveling engineering at some point. There's probably a good bit of gold in them there bank tabs. Enough to pay for a dual spec so she can go prot/ret? Probably not, but it worth it to check, at least. Going prot for dungeons and ret for questing seems like it would be the best of both worlds.
