Honestly, not sure what would really help at this point.
I remember back in 2013 the zybez clan discussion staff at the time was allowed to talk to mod mark on skype, and looking back, we've achieved a lot that wasn't really supposed to happen.
Putting an official clan system into the game could really help, along with all the clan information that'd come with it(clan exp, deaths, kills, ect). At the time when it was first introduced pre-eoc many people questioned whether it truly benefited pvp clans as they felt it took away many mains from the scene who'd rather be in "clan chats" with their friends than join actual clans. However, it puts pvp clans out there a lot more, and it'd give them more tools to better the quality of life we have with clans at the moment.
Edit: Also bringing back the jcup would be good.
