What's the rest of your CB team?

Generally speaking shes a better support champ, but you do lose the Dec def from Tayrel so depends on the whole team.

Ghrush, Ninja, Dark Elhain, Tayrel and Skullcrusher.  I do about 85,000 on a 3 key Ultra Nightmare

you've got ninja providing def down, so it should be worth it to replace tayrel with ss. you also should look for someone to replace dark elhain, as she's pretty rubbish for clan boss. post a picture of your roster and maybe we can find someone better.
