Yeah, similar to what the others said. For a churner it may not seem like much (ET mentioned 5/24 so maybe that's where they are coming from).
But as someone with medium organic spend and a fear of true churning, this is a great card for me. It seems like the ROI is actually higher than most of the churning SUBs, although I'm no expert. But the caps are probably lower, so if you MS then maybe it's not worth your time. (But then why not both?)
