I honestly forgot about the Stealth bubble, I never actually used it last edition.
The thing with his earlier redeploy rule was that if you deployed second it didnt matter, and if you deploy first and your opponent just sits in the centre of the table, etc, it really didnt matter either.
With scout, you can make it ALWAYS matter!
Agreed the Warhost synergizes really well, especially when you consider he gets that guaranteed 6" run roll as well.
Even so, I'm not strongly considering the big E-man right now =/
