I'll be honest that I traditionally don't care too much about team comp and figure a good crew can get in and out of any situation, though I do recognize that it is an attitude that some people find distasteful. 

Tis why I usually end up asking if people think we are lacking something in particular. Normally, the answer I'm most familiar with ends up being 'a dedicated healer'. XD

(Always could go with http://whothefuckismydndcharacter.com though that seems a little too absurd unless we have a full group going all in on it)
