-Definitely more quests. I saw on page 1 that this is all ready being done.
-Less grindy. Skills should definitely have many ways of raising them. I always resented how the only efficient way of getting a high wisdom was to just spend hours making dov or dopv, w/e it was.
-More lore-friendly. What happened to the faeries and dwarves and such that we read about in the lore books?
-More weapons available to average players. It's always been a big issue for me how 1% of the population (.. so 1 person basically) has most of the extremely rare items and can make hundreds of USD just because he either used USD himself, or has played for years and hoarded items. This issue has been partially fixed with the new tigbot, but i definitely believe that new ways of getting weapons, as well as a server-wide reset, should be issued.
-more fun , rewarding jobs. Currently fishing is only good for a bit of food, mining only if you're building a house, etc. I saw on the first page that this was all being revamped, but it's definitely something to be carefully looked into and revamped.
I know a lot of these points (if not all) has been brought up already, but they are just what i feel needs to be done for the future of GK. There are some obvious ones like more staff, classic, etc., but those are all ready being planned for
