Why can't you switch between "advanced classes"?

Where we not able to change our AC before f2p?
I forget most of my time playing then as i rushed through everything.

Though that may have been a pre lvl 30 thing back when AC's didn't open up till lvl 10.

Some bugs are a whole lot worse than others. I think the class and peoples personal game play is on the top of the list.
Why change something that works fine now? Just level the other class.

And the crew skills too?
And play the same story over again just for something as simple as a advance class change?
And get all the same items that were grinded to attain?

Again, if all you do is PvP I could get that. But outside of that start over from scratch is a dick thing to say to someone. I'm not a heavy PvPer so I may be out of touch, but even they have things they had to grind to get, right? I know Warrior/Knight is kinda screwed either way in that department, but not the other classes.

The issue isn't if peoples wants it or not actually. It's the same reason as why you cannot change your character's gender.
The game is built in a way that resolves around advanced class. Each quest reward, each cinematic, each raid, each pvp is based around what you could call an advanced class data.
It's the same as when opening a command crate, the game basically look into your character data and search for the indication if you are a sentinel, or an operative for example. Doing so would demand to rework how every reward in game is given, this includes Operation rewards, class story rewards, ranked pvp rewards (unique titles for the top 96) and a whole lot of other things. This would also demand to rework most of the cinematics, who includes your character wielding a defined weapon and else, along with some other changes that resolves around advanced class. Too much work for little result, not happening imo. ^^

The issue is not to do so, but more that you won't be able to implement this in the game because of how it is made.
Rework entirely the game then maybe we could implement this.

I think we just have to agree to disagree, even if others don't share my point, almost nobody in this thread seems to be on your side with this. I'd just give up at this point.
Sorry if I seemed offensive by saying just start over, I didn't mean to be rude. It's just what I would do.

Give up?

I don't think you understand what this thread s about. Your opinion does not matter. My opinion does not matter. The Devs are not going to do anything because of this thread. So I don't need your approval for anything. It's not up to the people in this thread.

The point is to find out if there is a legitimate game mechanic reason why this is never done in any MMO. Not just SWTOR. I'm not trying to convince you or anyone of anything.

No, you're not being rude to me. I have a character of every AC type. I'm not looking to change ACs. This is not about me.

Because it would be weird in roleplaying terms.
"Oh yeah, my character has been training since childhood to become a healer. But now, by pressing a button, he can convert those skills into being an invincible engine of destruction"
Makes no sense.
On top of that, you can change the discipline, which usually offers some focus on the three traditional roles each.
