Nope.Here is my issue...
Why have a melee character with STR at all?
With the Rapier rules you can have a d8 melee weapon AND cover your AC with the same stat. You can "dump stat" your STR (or at least minimize it for heavy armour use) and still get your full melee bonus'. The long sword has become obsolete!
Thematically, it's even worse!! You have a bunch of plate armoured fighters running around with fencing weapons AND A SHIELD!??!
I don't understand why the change happened (other than someone's fetish for steampunk style thematics) instead of just leaving the Finesse Feat in the system for people who wanted to be DEX based. If this was all about the Rogue/Swashbuckler, then make the Finesse Feat a class feature at 2nd level. Personally I'll be house ruling that finess only gives DEX bonus to to-hit, damage bonus still comes from STR. Or, maybe I'll just say that you lose the finess feature if you use a shield. Or both.
Either way, the Rapier is a "broken" feature of the system and needs review.
I am fine with them.
That said, I prefer the d6 light finesse weapons myself.
I just dont get all up at arms over a single die step difference with loss of light.
