Obviously, you've been fighting the same people in the same ways for years.
There's a post on the front page of reddit right now which addresses both the clan world's stagnation and Jagex's desire to stream pvp competitions while being completely clueless as to what those are supposed to look like. I've never even been in a main clan and I haven't played the game itself in years but I found the suggestion of the clanning world reaching out to Jagex to help create streamable pvp content when they're desperate for it to be an interesting one.
They've never listened to you before but this is a unique situation where they're actually looking to rot for guidance in how deadmanmode should end. You could possibly work with them to create content which compliments and reinvigorates how clans war.
