Ok adrian, im riddle i already sudgestion one of these to you but i will repeat it for the feed back.
1. EXP bonus weekends, from friday to sunday a skill recieves double exp! making it great and maybe people will skill even more!
2. After achieving a certain amount of exp, lets say 500m exp. A player gains veteran status, this doesnt give them any bonus other than a little crown like a mod, and when they log in, it might say, verteran such and such has logged in.
3. add seeds to a shop, lets face it no one wants to kill for the seeds and it takes atmosphere from the game, if seeds where is shop it would encourage more people to farm and level herblore, this is good for rapescap3 and the individual players
4. add kalphite workers, so far there are non on the server which makes 99 slayer unobtainable, this is unfair for some as they have higher slayer than others with the task, 99 slayer is a fun skill to get and would add greatly to the server.
5. LASTLY, RUNECRAFTING! this is currently the only skill untrainable to 99, and it would make for an awsome race to see who can get to 99 first :p, i myself cannot code it but i have many friends who are experience in coding this sort of stuff if you need help
Thanks for the time and hope to see some of my updates in the future!
