For a rogue, in this specific case a Thief, is there any reason to prioritize the use of dual daggers as opposed to dual short swords, or a rapier?
I am running a campaign and the party rogue has decided to keep his dual daggers instead of changing to dual short swords or other options. I have tried to find any instance where daggers have some form of advantage (beside the thrown property, which he has never used and is unlikely to, based on party composition).
I found a question that answered that dual daggers might yield more damage per round than a single rapier, but are short swords simply better? Or have I missed something? He is more familiar with 3.5e, so perhaps he is superimposing an old rule?
The next part of the adventure provides a number of +1 weapons that no one can actually use, so I plan to substitute them for more useful items, and hope this can help inform my decision of what to give him.
