"Lets group together"

I feel like people should just stop saying this. In nearly every single game I've played as a low elo player, anyone who ever says just this, or something similar to this, is almost always that one person that runs off alone and dies. Just a mild dose of advice for anyone looking to rank, or at least may consider trying it soon. It requires cooperation, trust, and understanding of each other's play style to at least a point. So if you impose yourself as that person that desires to stick together, please bother to heed your own advice.

From hindsight, this feels like it should be obvious, and could actually be applied to a variety of things, but it's too common. I see it too often, it needs to stop.
