The Countdown is running, on 1.1.2012 we will start our new crossover-campaign (DH,RT,DW) with BC Rules.
And as soon as First Founding was available for my players one of them had the idea of starting as a Wolf Scout and to develop it into a Kill-Marine.
Personally I love the SW's and I find the idea of combining a Lone Wolf with the capabilities of a One-Man-Kill-Team very pausible though by RAW he will be stripped of all Fellowship-based Talents that distinguish a Kill-Marine and the most obvious advantage will be to use some Squad Mode Abilities without the support of a Kill-Team but I also noticed he will get acces to some most crucial skills for a Wolf Scout at a much lower cost.
Every advancement for Concealment, Silent Move and Shadowing will only cost him half as much as an ordinary Wolf Scout and on top of it even though his Behind Enemy Lines Special Ability prohibits only the purchase of Fellowship-based Talents I'm not really sure if this could also apply to an Advanced Specialty since a DW Kill-Marine has the Prerequisite Fellowship 40+.
So by RAW I would support his idea but maybe I should raise the cost for all Stealth-Skills. What do you think?
