1) Final Fantasy XIV around the corner-- they would like to retain XI players, and allow them to play both smoothly.
2) Progression from "old" content-- most everyone that reads these boards along with Alla and KI will agree nothing is exceptionally hard in this game anymore, sans Vrtra which is a semi broken HNM, PW that needs members and a well planned out strategy, and AV which is half plotted out, and half unavoidable bullshit. Can do new exciting level 90~120 fights vs HNM.
3) Giving "normal" players a chance at current loot.
4) Reviving the game in part through new leveling up and meriting. People love doing this, don't deny it lol.
5) Allowing the unfortunate (see: "lazy") people hand-holding venture through soon-to-easy missions with higher levels. Well, and finally coming to terms with the fact that they fucked up with CoP level caps.
