I suspect problems soon and I don't for a second think this is common to BDR only. I have put 12k on mine and changed the fluid 2 times over the last 2 1/2 years. I do have the heat shield but I think even with this the real issue is cooked fluid and changing is the best solution. All these cars run extremely hot and eventually it will catch up to me and I will need to change the slave, but hopefully not this weekend.
