Even on bosses Chaos Bolt makes up a large chunk of your damage as you should be pooling 4 embers to start most bosses--so once again Crit is top dog.
It's not necessary by any means, but Copeland's is absolutely insane for the same reasons that I exalted Crit.

Edit: No other spec comes anywhere close to Destro in CMs, don't even think about using Demo or Aff!
