I plan on subbing. I did only do one month, because there are certain things I'm worried about like combat changes, how fun leveling up other classes will be, but most of all: I want to be able to transfer servers to play with friends.
Once server transfers are available, it's just minor worries that only time will tell. So far, I've really enjoyed the game. I can only imagine how much better it's going to be once I can play with my friends!
