Well seeing those new huge marine models made me happy. Lots of people already hate them - I think they look awesome - I mean look at the size of those things, look at the load of conversion parts, I cannot wait to get my hands on those. I'll be putting my praetorians on pause till I get a hold of those legs, that's for sure.
But also on their own part they are cool in my book, and I could see them appear in my Iron Ghost army - I could easily make them fit the fluff.
