I'm a little unclear on when you're saying you're using your CC breaker, though - is it on the knockdown? I don't know if that's the best time to use it (using a CC breaker to get out of being incapacitated for two seconds isn't as useful as it could be elsewhere).
If this guys right that's one thing I can say for sure... eat the spike and save it for the hard stun. You're gonna eat some damage in the beginning. It's tough too cuz they'll almost always start from stealth so you can't even pop a DCD before getting spiked into the ground.
