Hi everyone,
would you allow a character with Improved Unarmed Strike, Improved Grapple and Weapon Finess to use their Dex bonus with their grapple score? My friends who study Aikido would certainly say strength wasn't a factor in their throws.
My opinion: No. Strength, skill and conditioning are much more important. Dexterity and finesse will help in some situations, but strength and skill will help in pretty much every situation.
