Game is a good start and I see tons of potential but here are my gripes in order of importance (to me)
Grouping and guilds. You have to be able to share access to things easier a guild member asking you to open the gate every 2 minutes or building a big house that one person can claim, etc... I am sure everyone is asking for this
If you are grouped with people maybe an icon over their head letting me know they are in my group?
Right click needs a larger ability area. Everyone walking around looking straight down clicking at the ground not only looks dumb it is agitating.
Default actions need to stay locked to the default.
Better target names (NAMES FIRST) and fonts on targets. Since all the character look identical it would be nice to see friend/foe with a bit more ease.
Better tool tips without having to go to the web or wiki. Maybe an info button so if you want to make say "Linen rope" there is a tree of things that show you all the steps you need to generate that item.
Teraforming elevation grid should be a toggle that you can just leave on because digging is so much fun who wants to pause?
Day and night light availability need to be balanced better. Me just maxing out the brightness at night seems silly.
Some type of "kill report" with who killed you with what damage and what loot you dropped.
