In the midst of a mostly unrelated post about the Druid Balance tree, Ghostcrawler let slip the following: "The dual-spec feature will shine more light on talent design (more on that at Blizzcon) and we'll have a better idea of what we want to do with trees when that goes live." Now I don't know about you all, but as someone who plays a healing class for a main, I am very interested in the dual spec idea. Knowing that we'll get more information on it at Blizzcon, just a few days away, makes me a happy priest indeed.
But what could she mean by the dual-spec feature shining more light on talent design? It's a slightly mysterious statement, but my interpretation is that when everybody can have two specs and switch between them either freely or at least cheaply, the load each spec needs to carry lessens. It's OK if Holy can't solo, because you can just switch to your Shadow spec for that. It's not such a big deal if Combat isn't as strong in PvP; just swap out to Assassination for the BG weekend, and swap back in time to raid. The trees no longer have to be strong in all areas of the game. But that's just guesswork on my part; GC may well have meant something else entirely.
Either way, we'll see in Anaheim this weekend, and WoW Insider will keep you posted with live reports.
