So, set up a totem farm in front of the shaman and step back a few paces.
When the dk has death gripped you through the totems you are still within their range.
So if you had tremor totem(s) in the mix it would break fear as quickly as normal (which may nor may not be too quickly depending on pulses).

So - in the above situation your tremor totems would provide the same level of protection as they always did.
