I think they might add dual-specs at some point. But only a dual-spec within your AC. They should not allow changing of AC at all. I'm not sure if the OP meant re-speccing in the same AC or switching. Right now, you can still go and re-spec whenever you want for a fee, within the same AC, of course, just like they had in WoW for the first 2-3 years of its existence. People survived then with it, so I don't see why it's necessary now. Plus dual-speccing is only really needed for endgame stuff, and not many people will get to endgame for a few months in TOR.
