I have a Warlock in my group that rarely ever gets his pact blade out, since it takes an action to summon it. Given that drawing a regular weapon doesn't even take a bonus action, is there anything in the rules that could break if I allow the weapon to be summoned using a bonus action instead?
The use case is to seem as harmless as possible - none of the Warlocks features are openly visible or rely on bulky equipment. But if there is a fight, time is of the essence and wasting a round's action on calling the weapon seems too ineffective.
