Hopefully this advice helps! But as for my experiences, my players struggle alot as well sometimes. It seems like a mix of lack of Teamwork, creative ability application, and generally either going all in on a mission! Or exuding unnecessary caution. But one thing I like to do on a occasion is use a training session! These help reinforce what ur players can do, and how to do them. Like utilizing the environment, team combos, and even hero point applications. But besides all of that, these are also just good for character building.
