1) Interface upgrade. Make text scaleable, item descriptions should be accurate, guide npcs should have correct info, ability to color different chat channels differently.
2) Expanded and re-balanced PVE. Make the world fun to explore again. There should be multiple places to level at most level ranges, with different unique loot (DOY tunnels are a good example, but currently not really viable for someone to level at). PVE that ties in to storylines would also be very cool. Obviously making entire new areas frequently is not feasible workload wise, but having some areas built that are re-purposed and populated as the story line changes would be awesome. Outzone is really cool and should have more to do (I don't just mean having missions forcing people to run thoguh). There should be rewards for exploring the world of neocron.
