What the game should have is more midgame content, I don't blame SE for adding so much endgame content right now because most players who are subscribed are at Level 40-50 on several classes, and so endgame content is most important to them.

As well as alternative ways of leveling other than grinding - I don't care if grinding might level faster, despite being monotonous. If there was an alternative way to level, say through competing in PVP or a type of Conquest-esque system (even if these two were, in comparison to the grinding, a slower way to level) I'd PVP and Conquest more than grind.
