They actually tell the fighters for more action regardless of position. Note Holly Holm vs Bethe Correia where Marc Goddard called for a time out in a fight with only stand up.
I'm ok with stand ups, I'm okay with crow booing (what happened to that?) or the ref telling you to up the action in a round where no one throws anything.
MMA is still in it's early stages, and ruling and judging is still pretty backwards and incosistent.
Yeah not sure what they're doing with that. I have a bad feeling the next patches will be: "what's the current meta, and how do we nerf that."
