As little "interactive world" as possible, the low interactiveness at the moment is what makes it so easy to play even at long distances and with bad connections. If I have to jump over obstacles or slide under barricades, it'll be harder to play with my friends on other continents without insurmountable lag.
--------------------------------
More useful guild halls. Make them a hub of operations for the guild, with options for various sorts of high-level PvE combat and "safaris." Allow the guilds to be expanded with new land, new structures and new NPC's, both decorative(Random wandering citizens and peasants) and useful(Smiths, trainers, agents, captains, etc.).
--------------------------------
More living landscape.
The roads in civilized nations should be clear, there should be living villages, there should be travelling traders. Raiders should occasionally hit the roads, bu they and monsters should generally be in the wilderness, kept off the paths by guards.
Monsters should also have settlements of their own, camps and caves that they'd fall back to defend, send out patrols from and keep their best loot in. Maybe they'd even have their own small farms and such, in their homelands.
---------------------------------
A living ecosystem. If everyone keeps murdering a disproportionate amount of Tengu in an area, but sparing the Ettins there, have more Ettins spawn and less Tengu. Have the Tengu start spawning in adjacent areas instead as they are driven out of their land, and the Ettins start taking over their encampments and such.
Make it harder for people to just keep sweeping through the same areas over and over again, have them change and vary.
---------------------------------
Allow appearance stuff like hairstyle and such to be changed past character creation.
