Haven't played WoW since early Cataclysm. However, back then WoW just as well had these issues. Even with a hard mode raid and regular mode raid, people still failed to find groups for the normal modes. Based on gearscore they'd quickly be kicked, etc. Many claimed the fights were too hard in the normal mode. Etc.
I've never experienced the raid finder raids, so perhaps that those are a pushover with a difficulty of ST/CT runs here. Can't say.
