I think you guys are seeing this from the wrong point of view. All these changes are not to fix issues now, but in the long term of the game.
Leves are no longer the main theme of the game. By the time they start charging for the game enough content should be there for anyone who starts to almost have no time at all to do leves.
For the current players, sure, its not enough if they are playing constantly, but really nothing in the game right now is enough. Try and think about when the game is ready for fees if you really will complain about four leves every twelve hours. Leves are no longer for the hardcore, but specifically for the casual player who will log in after a days work and most surely just log in to the leves, maybe two or three before continuing on to do events or any other type of content.
All changes done to the game are thinking ahead when other content will be more important than leves and you will be logging in today to do raids and quests, tomorrow to do primal battles and large scale PVE and days after tomorrow, sure lets do leves, wow, you now have like 24 leves to do !
