Skaven are probably the most unique / original idea in the universe (not super well-versed though, so correct me if I’m wrong and there’s tons of rat people precedents out there), but Lizardmen have always been my favorite. They’re so colorful, plus dinosaurs!
I voted for Lizardmen as I’m leaning towards them myself. They seem to play a bit like Dwarves in the ways I love Dwarves (fewer, more expensive and powerful units and lots of technology to research) but also have powerful Magic to boot. Also, dinosaurs.
Hey, I’m totally down with Lizardmen! I’m just trying to read up on ways to better control rampaging, or how to restore them to sanity quicker post rampage.
