I also found the game a bit boring around level 25. The world seemed to get more dense and smaller as I progressed, so I would have prefered much larger zones and no barriers for the whole continent. Leveling is a bit fast for me and the mobs also got easier and easier as I progressed, so a bit of tuning in that regard would be nice. Questing got very boring around level 20 but that I had already assumed that before I started the game. No comments on PVP since I find it pretty boring, though I like getting ganked on PVP-servers and carrying a grude for months on end.
Other than that I think it's as good as it gets at launch for an MMO in this genre. It'll be interesting to see how much effort Trion Worlds will put into the game post-launch. Some good points about the game is it's story-quests, the roaming mobs, and rifts. I didn't play a lot of dungeons but what I saw seemed pretty decent. The soul system is refreshing and I like how easy it enables different roles.
Atleast it's not a half-baked game as Conan was, where Funcom even gutted half its team right after launch to work on an expansion.
As for my MMO saviour, my hope lies with Carbine Studios' generic fantasy MMO.
