Sadly that's life. I'd love to travel more and play more games but work, my daughter and any number of other things prevent me. Can't exactly whinge at my boss that my job is getting in the way of my raiding, nor do I think my daughter will understand if I suddenly take off to see the world.
If you have responsibilities that prevent you raiding chances are you're an adult, and you should just deal with this like an adult. My shifts got changed during TBC and missed out on raiding Black Temple, I was gutted but I certainly didn't QQ to Blizzard that I should still get raid level epics.
