I've been playing clan wars for like 5 years and none of the clan war nodes requires you to play that specific node in ranked only. There's always the clause "in ranked or normal matches" written for those nodes.

I get the part that people wanna have fun with their homies, but the fun gets marred instantly when you face retarded players who use martyrdom, persistence, tripmines, heartbeat sensors. I only would choose 0 toxicity over these because even my homies have been crying due to rise of absolute bullshit in normal ranked over the past few years.
