Being a experienced MMO player i believe that what keeps "some" players including me happy is GUI enhancements(being able to make your own UI and use different fonts and sizes).
I have my game at 1240 by 1024 full screen, the text in my chat window is too small to read and the font is Terrible(i.e random spaces and skinny lines). Now Everquest the first one has the ability to make your own UI and it makes the game more personal in relation to someone else's. And being you can change the fonts, move the chat window, SPLIT chat windows so you have multiple chat windows in-front of you so you can absorb more information faster. Colored text make it easier to spot damage and such like it is now, but making different channels for people to talk privately with them selfs is nice. So groups and Clans can collaborate privately. And WoW did this UI customization and not only does it make the game more enjoyable it creates new communities like "www.curse.com" witch is a UI site for WoW. And one more thought I have before I leave this fat suggestion is this "the mouse sensitivity is junk, and i think the FOV of the game is bad".
