I think the only one who failed was the OP lol
My favorite excuse ever was a guildy who left a failing pug lowby group, with the best excuse ive ever heard...
"Sorry guys, I just cr*p*ed my pants, i have to go"
That should totally be one of the options.
And to the OP, thankfully, DDO is not a socialist republic, where your betters get penalized for your underachievements.
