I've not started on mine yet.
I'd like to see them still sold as a 'box set' so to speak, with bases included BUUUUUUT I can see why its not worth you doing that- someone that only wants one or two sprues isn't going to want to buy a box of them, and not everyone will want the bases/pay the additional cost for bases. From a selfish point of view having the bases included would mean I'd buy more- I'd rather buy a box of minis that come with bases, then pay for the bases separately, when I only needed the bases. More for your money kind of thing. (I use a fair few of the bases- but for other things)
But personally I don't think that having bases with plastics is going to increase your sales so much that it makes it worth putting bases with it. I've said it before- but I'd rather you charge for bases, make a little extra profit and still be here in years too come.
I was always of the mind that bases should come with figs- years of buying other miniatures supplying bases made me think like that- but almost all 6mm (and 10mm) don't supply bases and no one seems to mind.
Sell it all separate, stay in business.
Oh, I would like to see an option to buy the AA guns separate, but again, if I have to buy it with the plastics so be it. I can always make use of them- more dead humans for the base god!
