well, on the bright side it is free and it doesn't look like you have to worry about leveling. On the downside, it's basically scenarios and pared-down models from WHO. From the looks of it, you get 4 skills at the bottom of the screen, and it is 6v6v6 so a single side won't (in theory) always faceroll the other. The interface looks dumbed down (makes sense - it's just scenarios), there's no leveling that I could see, and you can change classes in battle (probably after you die). In essence, it looks like the kind of game that EA Mythic should have put out to test and optimize their scenario tech before the game came out.
I signed up, but honestly I don't hold out any hope. If anything, this crap has convinced me that SWTOR will undoubtedly suffer the EA curse.
