You may hear a lot of complaints about the graphics. I'm not one of those. Content and accessibility are much more important than trying to keep up with the latest, greatest graphics.
In no particular order:
1. Get rid of the some of the archaic time synchs. Quality content(which the game has) is better at prolonging subscriptions than frustrating time synchs. You built a large, wonderful world to explore, then you made the pace of walking through this world just barely above the need to visit a dentist. Increase walking speed on open terrain. Also, remove the speed penalties on cargo pods, or allow recall with them. One or the other.
2. Increase the weight limits on the vaults. Make it feasible for us to actually use the vaults for storage. I get my hands on some materials that I feel I will need in the future, but can't store it, because vault weight is a premium.
3. I understand the feel for the need of a separate RP server, but right now, the populations are so low, that player economy is almost non-existent. Combine the servers, if possible, for now.
4. Step into modern gaming with the consignment merchants. Let each one be universal, so players don't have to hop all over the place, searching each one.
5. Whatever you do, please do NOT give in to the PvP crowd. Or, if you do, make it some kind of arena based thing, with the rewards only being aesthetic for bragging rights. I have 14+ years experience in MMO's and PvP typically increases the amount of abusive players. I only have a total of a 4-5 months in this game, over the years, but I never asked a question in chat and got a smart*** reply in this game. The community is friendly, helpful, or at the very least, keep it to themselves. PvP tends to attract griefers and l33t d00dz. No thanks.
Just my two cents worth. I'm sure you have heard it all before, but this game is awesome, in the way it presents the crafting, multi-classing, and especially the dragons. Let those qualities sell your product and get rid of the speed bumps holding you back.
