Best 4th to add to this group..

Right now we have 4 people (Three Actually 4th is about to start).

We have:

WC
SWS
Destroyer

What would be best to add to this group?

I was thinking a healer would give us the best chance to do KAMA without having to depend on anyone else. I dont think a tank would be any help without a healer.

What do you guys think?

what kind of party you want? raid or farm party? i would suggest to get an ee because of clarity
