COuple of things.
1) i think saying that WoW has moved to a 'partial free to play model" is hugely disingenuous. Wow has a demo-mode that allows you to play the first 20 levels out of 90, considering that it takes less than ~10 hours to get to 20 and well over 150 to get to the level cap - which is where all of wows content is - that cannot by any stretch be considered a free to play model.
2) TOR failed because it was WoW. I played wow for years and quit about 10 months before TOR came out. I played with a group of friends that i had played WoW with as well, all of us refered to all of our class abilities using their wow names. I cannot think of a single ability that we had that there wasn't a direct wow analog for. There was next to no original thought whatsoever in the actual gameplay design. Its as if they thought that the shininess of lightsabers and lightning would be enough to carry the whole game. If you want an example of how to build an mo that tastes nothing like wow, look at GW2, I'm a loving hte living crap out of that game so far.
That said, once it goes free to play i will definitely reinstall just so that i can play huttball again.
