I completely agree. A solo queue multiplier for kp should have been implemented long long time ago. One thing solo players also deal with is sitting in broken MM where you drop as duo or solo, back out and go back to lobby. Happens way too often and is complete waste of time. "Looks like you played handicapped here is XXX (xp etc.) as compensation." I don´t know. Just food for thought.
What I meant by my post was that a banner, tracker or whatever would show solo player base that Respawn is actually looking into this and taking the first steps. It just looks to me like after six years the time is running out. Maybe Respawns focus is already somewhere else and these bigger TTK changes etc. are just a desperate last ditch efforts while they could solve core issues that drive players away from the game.
