1.) Getting 100k exp + for a single skill point is unreasonable grinding... Add a npc who sells skill points for money... This will serve several purposes... It will a.) Fix the skill obtaining grind b.) Add a sink for end game money thus increasing the value of the ever dropping gold c.) make me happy :P
Price it at say 1000 for the first point and double it for each one after that capped at 20k... so 1k,2k,4k,8k,16k, and 20k for each after that...
Makes it reasonable yet difficult enough to have merrit (ok I've got several hundred K gold so maybe lower prices would be better for everyone else but whatever)...
2.) Fix the NPC noclip bug... Either add a 'return to me' command where you teleport them to your location once per death, or add a 'killnpc name' command to end the game ending pve bug where they go all superman on you and fly away. They have been aware of this issue since the betas and still have not fixed it.
3.) Add more collector locations, with more collector items from the PVP arena's... It makes no sense for pvp characters to get way better equipment that pve ones (without dropping 100k+ on each piece)...
4.) Put up a new town with the exclusive purpose of trading... Say Traders Villa located out in someplace where nothing else is and accessable to everyone... Instead of districts have quality of items, dist 1 = to low grade dist 10 = to +30 pommels, sup runes, and the such...
5.) Not that I care but enough complaints and questions to warrent it... Put a 'viewable' look on each of the 15k and rifts/underworld armors... priced at 5k to take a look at one of the complete sets so ppl know what they are getting into, and not so cheap that every little kid gets to see them

Like your ideas... some have been dicussed before. But I like them nevertheless.
