I have only tried the free to 15 thing, but the class quests seemed interesting. I will be returning once the full F2P is added just to see the class stories. I don't have any interest in their endgame but if the 1-50 is free, I will have some fun with it.
I found that they were offering free server transfers from low-populated servers to... just one server. Yeah, all the low-pop servers were transferring to one other server.
They are mega servers. It's technically one server, but in reality it's got the capacity that far exceeds anything WoW currently has.
Anyway, I just resubbed TOR.
It's ok, but I've not been playing max level. Working on a new toon.
It's certainly better than GW2.
