I would add weapons to this list - if you are not using weapons specified for this raid (i.e. void) then you should have a good reason. Running around with a solar shotgun and wondering why minotaurs are pounding you into the ground is a facepalm moment for the rest of us. There are few exceptions to this rule (Ice Breaker for example), but in general, you should be using weapons that are suited best against the enemies you are taking on. If you do not know what an enemy is vulnerable to, look at it's shields. Hive Wizards have an orange-y shield, hence they are vulnerable to solar damage. Fallen Captains have a light blue shield, hence they are vulnerable against arc damage. Vex Minotaurs have a purple shield, hence they are vulnerable against void damage. Why is this important? Praetorians and Minotaurs are a pain. Period. Half of that pain is their shields. Dropping that with one hit from a fusion rifle with void alleviates a lot of stress, not only for you, but for your team.
