I'm not sure that burning talons is considered a CC in this game so I don't think any of the CC rules apply to it.
I have been told over and over in other threads just dodge roll out of talons and you get immunity to it for a few seconds. I have never had this work a single time. Unless the immunity is less than a second I am never immune to it even from the same caster. I never thought it worked but this weekend I payed extra attention to make sure it wasn't a second DK casting it or something. I get put in talons, dodge roll, same one drops talons instantly, dodge roll again same one drops talons again instantly .. after four times I'm out of stamina so that is as far as I could test it.
