The units which performed well (even above and beyond expectations) were all tufted and flocked.
The units which performed miserably (I'm looking at you, you useless cuirassiers!) were only flocked, not tufted.
Aha! Maybe it had nothing to do with crappy generalship after all - those units were simply lacking the magic of tuftiness.
So, I've got 36 bases of foot and 12 bases of cuirassiers to add tufts to before my next game (plus the 4 bases of Blue Reiters which will be tufted and flocked today). Looking at my packs, I need to get some more of the Late Fall ones, so I'll have to make a trip to 4D Modelshop tomorrow. Once the whole army is tufted, I'll do an "en masse" photo-shoot for you.
