I maintain it was more an issue with basing their fight around spacing, than teaching via popups. I didn’t even mind the many enemies that had unintuitive concepts like feeding them grenades. Once you attune to them, they’re simple enough.

Even after they teach you all that about Marauders, it’s not just a matter of how to shoot them, and when - but when NOT to. Plus hoping for their AI to act reliably as described.
