I never thought to use Flamers or Burstcannons on my Crisis for example. But then, there was it. The Mach where I needed two Crisis with double Flames. A few matches later I played a double retaliation cadre against Orcs. And imagine what I needed? Exactly. Flamers and Burstcannons.
Even the odds are very small to need those weapons I would magnetism them. We have hat great possibility to swap weapons each game and to have the perfect tool, and I think the option to potentionally do it is great.
So,yes. I magnetism all weapons. At least 6. This is the double version or a standard Crisis Team.
