So playing 40K, it makes sense to magnetize at times because you get a ton of weapon options and it allows you to save on potentially having to buy multiple models for the same role. But it seems that in Warmachine you pretty much buy the model you want and thats that.
However I've seen guides to magnetizing the warjacks (particularly you see the topics to magnetize the heavy jack body type and the light jack body type). Can you normally buy different arms to make a Crusader into a Guardian by simply changing out arms?
I'm still new to the game and haven't really done much outside of starting the assembly of my starter box set. But before I continue with the jacks, I want to make sure that it is/isn't worthwhile to magnetize the jacks.
