This has probably been recommended, but I will mention it again. It would be nice to have a saved spec for your current talents to expedite respec'ing. It could be implemented through the legacy system by having players buy one or two saves after they purchase the pre-requisite field respec ability. The reason for having more than one is to provide players the utility of having to be viable in PvE and PvP in tank/heal and dps roles. Players who don't know what they want from their off-spec can opt not to have a save, but those who change over and back from two static spec builds will want to buy it. This will also give players time to learn how to play their first spec before giving them too many options, unlocking once they achieve an appropriate legacy level. If you can add buttons to revert to the saved talents on the bottom right of the skill tree menu, it would simplify things too, so we don't have the clutter of more ability buttons. A mechanism for wiping and resetting each of the saves would have to be available too, which could be as simple as an X option next to the store button.
