ETA on Advanced Class change?

In many ways the level 60 token is a better choice than an AC swap.
You get a second character (with an additional character slot included) with all the bonuses of additional storage space (free if you've made the small upfront cost of unlocking bank and inventory slots across your account), a second crafting profession and the ability to run an additional set of weeklies/ lockouts if you have the time.
There is the loss and you lose access to things such as pets, vehicles, titles, companions (including investment in influence) and crafting progress.
But for some players it is the association they make to that character that they don't want to lose. For a game that sets such stock in storytelling and making emotional choices (ymmv on how emotional, but looking at the annoyance the relationship issues with companions flares up I'd say many get quite an emotional attachment to their character), not to mention the connection a player has to playing the game with friends/guildies through a particular character.
I've always thought the meaningful part of character choice was the Class you choose to play and the role you have them fill, Advanced Class sits as a mechanical distinction to maintain balance across available abilities. The sort of meaning that could be ascribed to an AC choice is just as meaningful when applied to the choice of Discipline.

No.

I am doing it, not my companions.

So if I am the one doing the work the direct correlation is Advanced Class.

All The Best

One's physical build and even species used to be set in stone, too.

After playing through KoTFE I think it's safe to say that our personal stories are gone gone gone. Can we please get an option to switch ACs now? I have 22 total characters, more than one of each AC but I would still love to change up a few of them.

Sadly, with the insta 60 tokens, I think you'll be SOL on this ever happening. Buying a 60, makes Bioware $...freely swapping your AC, doesn't.

LOL I assumed this would come in the form of an "AC Switch Token". Shirley they wouldn't add a new feature unless it was somehow tied to 1000 or more CCs!

Well Shirley has kids to feed....oh wait.....did you mean surely?

All the way through this topic and very few have advocated FREE AC swapping. As far as I'm aware the vast majority that want this feature added are willing to pay a certain amount for it.
Either as a large one off payment that then allows casual switching or a cheaper one shot token.

It would be interesting whether the devs could use additional ACs to separate out the PvE (solo/group) and PvP (solo/group) design considerations.

Not totally against switching AC, but considering how easy they have made it to level up a new character, and with the introduction of the lvl 60 token, I don't seem them doing this any time soon. And with the story being the main focus, I think they'd rather you played through that again.

No point having them doing more work, when they can just tell you to level up another alt instead.

This is your paid for AC switch:

1. rename the character you want to switch ACs with to <name> <AC> (e.g. JoeShmoe Scoundrel)
2. record the appearance settings at an appearance change station
3. acquire a level 60 token
4. create a new character with the name <name> <other AC> (e.g. JoeShmoe Slinger)
5. set the appearance of this new character to be the same as the "old" one
6. click create character
7. get that new character to 65 (one SM Op should do it)
8. gear the new character up

You now have "one character" with two ACs.
