It's all about Saurus and Skink Skirmishers. Skinks and Kroxies are terribad because of their crazy unit size, huge price tag, WS3 fatties, and the whole T2 5+ save free combat res from stupid skinks.
Slann are still magical powerhouses, Steggies are great and plentiful, Saurus characters are cheapo beat sticks (Scar Vet w/ GW is how much? Awesome!), lots of skirmishers, lots of dakka, lots of good fighters, Temple Guard.
Great book, extremely competitive.
