The species/class combo list you're referencing is not accurate. If it does appear in the magazine, that's unfortunate.
My guess is that an enthusiastic member of the press wrote down everything he saw in the character creation screen which, as we've stated often, is nowhere near final. Occasionally we'll have species in odd classes or in all classes because of a bug or testing.
Hope that helps!
As with any game in development, everything in any current or past build is subject to change. It is important to note that no species/class combination is final until BioWare announces it. Thanks to Gerbo and Meglivorn for pointing out Daniel Erickson's comment in the Dev Tracker.
PC Gamer UK magazine released what they claim to be an entire list of species and compatible classes in the the latest build of Star Wars: The Old Republic in their May 2011 issue. What appears to be a humanoid wearing a face implant is referred to as a Cyborg, and according to the chart, Cyborgs can be Troopers, Smugglers, Imperial Agents, Sith Warriors and Bounty Hunters.
An entire rundown of species/class combinations are as follows:
Humans: Can play every class.
Zabraks: Can Play every class.
Miraluka: Jedi Knight, Jedi Consular
Pureblood: Sith Warrior, Sith Inquisitor
Chiss: Imperial Agent, Bounty Hunter
Rattataki: Imperial Agent, Bounty Hunter, Sith Inquisitor
Mirialan: Trooper, Smuggler, Jedi Knight, Jedi Consular
Twi'lek: Sith Inquisitor, Jedi Knight, Jedi Consular, Smuggler
Cyborg: Trooper, Smuggler, Imperial Agent, Sith Warrior, Bounty Hunter
It also makes more sense now thanks to an old Daniel Erickson post:
Just to clear up any confusion. Implants in SWTOR, much like in KOTOR, are not visible and can be changed out. They are a way to give more loot and stat options to characters without covering them in random art pieces. Except for the flavor name given to them, they function the same as rings or amulets might in a fantasy game.
They are not the same as the visible cybernetics you're occasionally seeing on player characters. Being a cyborg is different and a very specific choice that, as posters have pointed out, is not undertaken lightly nor commonly done in the SW universe.
Hope that helps!
More is covered in the issue, so be sure to pick it up. Hat tip to Shrivenx on the heads up.
