I've seen this on a lot of private servers before won't list for obvious reasons...
Adding a auto buy back untrades by speaking to untradeable guy and toggling on, can make it more of a money sync as in, it costing you more to auto buy back (%20 plus default price) and it will go straight in to bank instead of having to run to guy with cash every time you die.
not sure if this has been posted before, couldn't find anything on it.
Like in OSRS make it so Ardy cape and Explorers ring give you ability to tele to farm patches be a lot more bearable to do farm runs without having to keep teleing to home then speaking to wizard, when I can just use them. Obviously capes locked behind achievements points at the moment and ring is locked behind daily task points to, so you will have to actually get them first so not everyone will have them. (Be a lot nicer for Ironmen, EIMs who frequently do farm runs)
Make the Rev cave tele teleport you to where it does on OSRS up in 40 wild, Be a lot better this way as all the people who try to avoid running that way that camp cave 24/7 will be forced to take the much longer or dangerous route to get back to the cave. also it's kinda nicer to have as you won't have to do so much running to get back there either nor to exchange emblems (it'll just be risky running out)
