I think I'd lose my mind only ever being able to play a single role. As you already know and since it's been mentioned over and over again, you have to be extremely careful when it comes to picking your Advanced Specialization. Once you choose one of the two options you can not go back. Of course you can choose any of the three specs in that specialization but that may not offer you comfort if you make a mistake here. Trust me on this one, there is nothing worse than leveling up past level 10 only to realize you don't like the specs that are available to you. If you take my advice and want to do research on this before release I highly recommend reading over my class guides as well as using any outside information. Below are a few links that I've used to help me decide which class I wanted to play

Here is what you can expect in March and April this year of swtor credits(2018):

In those three games you started out as a basic class of some kind and you could better your class, usually at level 10, or you could take up a subclass. A lot of extra information to explain to someone who never played them before. In this case the basic class you start out with is something like a Smuggler or Bounty Hunter. Once you reach level 10 you will still stay a Smuggler or Bounty Hunter but you will have an additional specialization attached to you.?Each class is able to choose from two different specializations at level 10. You should read both of them carefully and even use outside websites/sources for information. The reason you want to make sure you are making the right choice is because once you have made a choice you can't go back. If you are playing a Trooper and you choose Commando over Vanguard by accident you will need to start a completely new character to fix your change.
