It was a mainly guild run and my son hadn't been asked to declare a spec as primary.

I guess it doesn't make a difference though - as my son was never asked to declare a spec, and this guy was only
saying my son was holy to justify his ninjaing.

I could only see us being in the wrong if the ordering of your duel spec determined this - and so wanted to check I hadn't been in the wrong.

Thanks for your response.
