I like it... Devastator (and Predaking) stuck out like sore thumbs in the collection. I reckon it's easier to get 1-2 downsize versions than 4-5 upsized versions.
Tranceblade's price range is about right.
I haven't de-combined it yet but combined mode feels quite sturdy. I was happily carrying it around using Long Haul's trailer as a handle with no problems.
The only issue I've had so far is Scrapper's head keeps sliding out.
