The problem I have is that they don't tag it Steve/Tony. When it's tagged, I have no problem. It's tagged, so I can skip them. Same with the threesomes. It doesn't annoy me to see the tag, it annoys me that I'm reading a fic, that it's tagged Bruce/Tony, that it says it's going to be about Bruce/Tony, and right in chapter 2, suddenly, one or both are contemplating how to add Steve to the relationship and there's no indication of it on the tags.
