Whatever, it is standard protocol in the biggest sub MMO in the world to be able to change the possible specs of your character. All the advanced class amounts to is a permanent spec. This design has zero lore value and was designed to create more grind. After you have the one mission revolving around the choice, it means nothing in the story. I love this game, but this feature is crap. I say let us have the ability to add both advanced classes for credits or CCs and have a button to change specs, just like WoW... you know, the biggest competition on the planet.
Also, when we change specs, the system should remember our button layout. The field respect is annoying, having to redo buttons each time.
The only things I miss about WoW are changing specs and the wardrobe manager.
