I'll just jump to the ideas.
-Mithril Gloves to the shops (For pures)
-7 Wave Fight Cave (Without Tokkul reward that would ruin the mummy minigame)
-Working ::AFK Command!
-More Gwd bosses (Nothing wrong with the current, but the day this server becomes number 1 on moparscape server list, bandos will be crowded. The drops should split to their own bosses [zammy drops zgs, z spear etc, armadyl drops ags and armadyl armour])
-Infinite arrow, food and potion supplies to shops (Alternative: reset after each 2 hours)
EDIT:
-Item worth 2,1b so handling money would be easier.
