ETA on Advanced Class change?

I'm sorry, but why would you even think that is is possible that he meant no free class (AC) changes?

Here's the quote:

Nowhere in that quote does he say that you will be able to change your class (AC). In fact, he specifically says that the introduction of disciplines " will not allow you to change Advanced Class, just Discipline". That seems pretty clear to me.

Although Eric did not specifically say so, it would seem to me that there are no plans to allow class (AC) changes at this time.

They are in the process of making things simpler for Ratajack, not harder.

If discipline bought AC change it would be free bioware will not make revenue, when they can easily sell the swap as a single use consumable on the CM.
I meant the new system will not bring free change but does not make it any less likely they wont introduce it in future.
Hence the *fingers crossed* hoping they bring it soon.

Two things;

First of all, with how quickly you can level a new toon to 55 with the 12x xp buff, there is no reason for an AC change.

Secondly, in todays livestream, both Eric Musco and David Demaree stated that when you select an AC, that choice is final. "You're done. You can't go back and change that. "

Actually, there is a reason. Getting a toon to 55 is not the be all and end all of the question.
This is a story based game and for me (and many others) many of my toons "mean something" to me.
For example, I have both an Assassin and a Sorcerer at 55.
The Assassin is one of my 10 "mains": he has a fully fledged backstory, motivations, mounts, achievements, gear, companions at max affection, etc, etc, etc..., that I worked hard for him to get; my Assassin is "important" to me.
My Sorcerer on the other hand is an "alt": he was created almost a year after the Assassin so that I could experience the Sorcerer Lightning spec first hand instead of just seeing it and he has nothing especial and "means" nothing special to me and has been "inactive" since he hit 55 (over 6 months ago).
However, the Sorcerer did show me that I enjoy the Sorcerer gameplay *more* than the Assassin gameplay (which I do enjoy and play regularly, but I find myself missing the Sorcerer gameplay).
When the AC switch becomes a reality, my Assassin will become a Sorcerer. Not because of "flavour of the month" reasons. Not because he was "nerfed". Not because the Sorcerer is "overpowered". Simply because it will mean that a toon that "means something to me" will also now have a playstyle that I have discovered I enjoy more.
I will continue to play with "my" Assassin until he becomes "my" Sorcerer.

"At this time.". Remember that phrase. It is the one constant of MMOs: things change.
Think about it: you have 4 NPCs on each fleet, a total of 8 NPCs, that are currently only used once by anyone: the Advanced Class Trainers.
Do you really think that at some point you won't be able to go up to them and, for a fee, reset your Advanced Class? "At this time" this isn't possible... but things change.
(If anything, the livestream showed just how easy it is to "reset" the Advanced Class choice. It is done at least twice during the livestream. )

They took a definite stance
Well if that is true i might quit sooner than i think this was one of the maybes that have been stringing me on. I have a story for each of my toons if AC switch does not come i would have to delete them and replay. (slight case of OCD hate it but have to do it)
GSF GSH don't interest me( did not even unlock the nar shadda one even though have been sub the entire time).
next time i get tired of the game might leave and imagine will not be the only one to do so.

Jumped the gun again
I will repeat again the disciple system with the current XP boost is the best time to bring AC switch( for cartel coins of course).

They never said " At this time." Simply that you can't go back. As for how easily they changed the AC, they also leveled to 60 instantly, and eliminated the internal cool down for an ability. Are you telling me those features are coming soon too? Am I going to be able to spam death field over and over with no CD? How about master strike?

Switching AC is not the same as the other examples you have given. If you believe they are i hope you are against adaptive armor, character customization and dyes and don't use them as a matter or principle.

Blizzard introduced a instant character boost and this game was supposed to be EA's WoW killer.

I never said they said it. I said remember that phrase. In MMOs everything changes. Remember when they said you couldn't change your appearance/race? Remember when they said there was no player housing? Remember?

Don't be purposefully dense. It makes you look bad.
The fact that they reset the AC shows that there is no "technical limitation" to doing it. The fact that you currently cannot do so in game is simply because they choose to not let you do so. "At this time.".
