Already had our discussion over Facebook PvP group, but TL;DR is win:
1) Our CC types are ineffective and expensive in time to cast against that comp
2) Riding the healer as double ranged is an awful awful idea, as its escapable, does not peel damage, and is a one dimensional guard that target!
3) every possible interrupt that we could get, we got.
4) HoT's also make CCing the healer even closer to being useless at times, especially since Scold basically heals only with HoT's.
5) In an earlier match, Scold mentioned that he was getting kicked for days, and could not get a single cast off.
6) If you haven't played as a DPS vs Scold, then don't bother to say something about free casting, it doesnt matter if you sit on him or not.
