It's at this point, I use various lore bits from the different versions of DND when it comes to races that need to be a bit more interesting in the game for lore reasons. So my Halflings follow in this regard.
IIRC in 4E, the Halflings actually had an expansive River Boating network so they were quite handy for getting around places when need be, aside from the usual Halfling stuff they were known for. And then in, Basic or another early edition, they actually had a whole expansive country/pocket nation called the Hin Dynasty, I believe and it was located within an expansive Halfling territory known as the Five Shires. And said members of the Hin Dynasty, certain ones, knew the application of a particularly nasty sort of thing known as Blackflame which meant that certain Halflings were actually Black Flame Zealots. Also, to add on to their River Boating nature, there were Halfling Pirates in the Five Shires as well.
And yeah, I used to feel the same way about Halflings or what exactly made them different from Gnomes, and vice versa. Thankfully, 4E helped out ALOT with that distinction.
