I use whatever I want.
I keep saying this, but miniature wargaming (at least for those who are in it for the long run) is not about the rules. It’s all about your collection of miniatures build up over the years. The rules should fit your miniatures, not the other way around 😉
20 years from now I will most likely play rules yet to be written with gaming mechanics yet to be invented. But chances are I will use miniatures that are already in my collection today.
Rulesets come and go, and have short turnaround times. Miniatures are forever, especially if you’ve painted them yourself.
