Agree that you should be able to freely swap between your equipped melee and ranged weapons before you make an attack, but are locked after the fact! As the game plays rn, no matter what weapon I attack with, I always swap to melee weapons before ending my turn so I can take opportunity attacks. Which is silly.
It should cost an action to equip a new weapon/shield/maybe jewelry. You'll be forced to weigh your decisions: "Do I spend an action to draw a bludgeoning weapon that will do more damage against this enemy, or do I keep equipped the piercing weapon the enemy is resistant to and instead use my action to attack/throw a grenade/something else this turn?" 5e RAW you can draw a new weapon as a free action if you drop your equipped weapon, but I think that's too complex/unintuitive for a video game. Plus, that adds more stuff to pick up after a combat ends which this game definitely does not need.
You should not be able to swap your armor/helmet/boots during combat. Really, right in front of enemies who are attacking you, you're going to take off your helmet? Really?
