I like how different races have their individuality, but at the same time you have little quirks such as...

Weight sensitive switches in Quicksand Caves. (1 Galka or 2 Hume/Elvaan/Mithra or 3 Taru to trigger)
Mithra can eat raw fish.
Galka can eat raw meat.

Those are all that come to mind at the moment, and I admit the ability of galka and mithra to eat raw meals isn't gamebreaking, they still have that tiny difference.
