TBH I think MMO's should just go the Buy 2 Play model from the beginning now these days. Similar to GW2 and now TSW. You buy the box, get access to everything, then can purchase cosmetic changes and services like name changes etc for RL monies along with things like optional quest packs that aren't the same as major content patches but just little fun mini-adventures.

(SWTOR's F2P model is horrific)
