Howdie, Contempt! Welcome to the forum.
I made a warband from the new clan rat and storm vermin boxes - the assassin and the two black skaven from the stormvermin box and the others from the clan rat box. The assassin and BS look great - but are really too heavily armored (in the game they cannot wear heavy armor). In our group, WYSIWYGis not a huge issue. The other problem is that these boxed sets do not have the specialized weapons you might want - no warplock pistols, no fighting claws, no throwing stars or knives. I gave the assassin a pistol from the Empire outriders plastic set, and it looks good, though.
Post you warbands in the "Rules and Gameplay" section, I think.
