Nope, never have had the need. At my tables, 'reach' is required so infrequently that none of my players have ever made a weapon selection based on trying to get that specific property. If they decide to go polearm for whatever reason, having the 'reach' property is a nice ribbon for that rare occasion it comes in handy... but it's rare enough to get a player of a STR-based melee PC wanting a polearm. I've never once had a DEX-based melee PC ever suggest wanting a finesse reach weapon.Out of curiosity, did you include a finesse weapon with reach other than the whip which gets crappy damage?
Edit:. And that is a simple weapon for non- martial classes?
Not saying other tables couldn't find a use for a "whip-ish" weapon on the chart (those games that do more dungeon-delving when having a front line and a line behind them with reach weapons comes much more in handy)... but it's never been asked for at my tables at all. But at some point if someone really wanted to go the Indiana Jones whip-master archetype... I'd probably make it work for them and adjust the chart accordingly.
