I've not commented, but I've read this thread with great interest for the last week or so. This tangent brings up an intriguing point about which I've wondered for several days now. I agree that as the RAW stand, short swords and long swords feel pretty meh-y, especially compared to rapiers for fighters with strong DEX scores.
What I've been pondering, though, is the matter of armor and its limitations in 5e. In the original AD&D, plate armor or full chain mail armor didn't kill your DEX bonuses the way they do now (unless my middle-aged memory is betraying me yet again). What it did do, though, was cost a fortune. I'm considering going back to that arrangement for my party's next campaign. But my thinking here is that the medium and heavy armor ought to come with some kind of additional restriction, so my nutty notion this morning was, "Well, what if such armor precluded proficiency with finesse weapons?" (Hand-to-hand only--let's leave ranged weapons out of the hypotheticals for the moment.) That is to say, suppose going with medium or heavy armor required also going with the STR-based weapons, but at the benefit of a killer AC; might that work?
Plate was generally non magical, platemail was common enough.
The enchantment bonus applied to saves the armor would effect eg dragonbreath.
+5 chainmail was a lot more common than +5 full plate which rarely was over +1 if it was magical.
