Fight Stat tracking - KDR, Wealth gained/lost, low and high numbers in game. Just anything that can be used to show performance of each clan rather than rely on word of mouth and cherry picked kill/ending pics.
Low level safe zones - Areas with banks in low level multi wild (25 and under) to help support the formation of low level cc teams which help the wilderness "food chain". Back in the day things like the FOG cave, BH stairs, CWA lobby were all examples of this in action.
Clan Chats - Move the 150 total level requirement to a CC setting that the owner can enable rather than limit it to every new account to help foster the growth of cc teams. W308 Varrock - Hills is super active with these 15 - 45 cmb CC teams right now but forcing them to train skills they don't have any interest in to take part hinders rather than helps the scene.
F2P - Stop ignoring F2P and add some content, there's a lot of interest in the F2P wild scene especially with mobile taking off.
