I have quite a few FW models and plan to purchase more. Yes we use them in regular and Apoc games. Stuff like iconic doors, shields and shoulder pads are not game changers, just stuff to dress up your army. As for game altering models we will work that out before a game and usually we will allow it, especially with our club. I like to use my nasty stuff so I have to allow my opponent to as well, no? If I'm playing a stranger then we will work it out, or not use that stuff...whatever.
If your plan seems to be working...something's wrong
