Well, it could, because grandaddy Warhammer FB was/is a skirmish game that piled up minis into units.
One of the things that put me off it, and WAB.
I did hear about WaC and CoE when they were released, but wanted to get as far away from Warhammer as I could. I can't be having with individual casualty removal in a battle game, anymore...
Well, there is no arguing taste, of course. One guy hates casualty removal, the other one hates counters...
BTW I tend to define skirmish as games in a 1:1 ratio (one figure, one man) where the smallest playing currency is a figure which accounts for me not seeing WAC as a skirmish game. If the smallest playing currency is a unit, like in WAB/WAC where single figures usually have no significance, it's not a skirmish game in my book.
