Loading two hand crossbows is heroic? How does that have anything to do with heroism? It's a power gamer exploit.
Anyone reading Crossbow Expert can see it was intended for a rapier wielding player or single sword user to fire a hand crossbow along with his weapon in melee. It's another example of a small clarification slipping by that gets exploited by power gamers looking for any advantage as they try to force RAW onto DMs to exploit rules.
Look at that, Crawford did clarify. I knew they never intended Hand Crossbows to be used like automatic pistols. Crawford agrees that you need at least one hand free to load the bolt. Like the new WotC says, your table, your rules. But it was never intended for you to use two hand crossbows and fire at will with the bonus action. It was always supposed to be one shot, enter battle, reload maybe every other round. Like a pirate or musketeer with sword and pistol.
