Yea, Pjetski has the right of it, I've seen so many different lists do well from SCE. In Orruks, everyone just ran Ironjawz at first, but now I've seen so much more being explored. I've seen Bonesplitterz and Kruelboyz both excelling. Nurgle also has multiple solid builds; the nurgle beasts build is really strong, but so are like two or three others. Nurgle stuff also has seen play in Legion of the First Prince.
If we're lucky the Fyreslayers' tome will be more like Nurgle's: the builds aren't immediately obvious, but with experimenting they start to really shine.
