Great Game, Minor details annoy.
As of this writing, the minor oversights that abound in this game are a killer. Simple UI bugs such as the chat window resize feature not working right and random repositions of it, unclear chat commands (Why isn't /1 in the list of commands to chat with along with /say, /party, etc?), no auto-skipping of the intro movie every time, EULA agreements every time you play, the password box doesn't automatically take focus when you start the game (you have to select the user/pw window with the mouse before you can type in it at all!), a crafting interface that's unclear about what you'll get when you create a talisman, etc... all of these are petty and minor, but added up, they equal less fun.
Even more concerning to me are the areas of realm populations and graphics lag. Playing on a low-pop server (I joined the first one suggested by Mythic to see where this would lead) has been hell trying to get a group of any kind, let alone get in on any RvR action. Even at peak times the wait has been 1/2 hour or more for a Scenario group as a solo player. They really need to combine servers (DAoC and WoW both ended up doing this for similar issues!) or allow characters to wander servers... Guild Wars and CoH did this, and it works wonders. They also need to display CURRENT realm populations rather than totals. Current stats are more useful in deciding which server to play on; a server may be high pop total, but drop to nothing at night (when i'm up usually!).
In the graphics realm my concerns have shot up dramatically. My system isn't flashy, but it's not a completely inadequate beast either (AMD x2 3800+, 2gigs, nVidia 7600GT). I can play in the "PvE" world at medium to all high settings with acceptable FPS lag (not much actually), and the world looks gorgeous. As soon as I join an RvR scenario though, the video lag is astounding and unacceptable, even when I lower to the game's "Balanced" settings. Performance shouldn't have THAT much variance that I have to change all my settings just for RvR combat.
Overall, a well meant and designed game... but it's biting the dust hard for me right now.
