I'm on the PS4, but I used the destinyLFG sites and was able to find some people without a problem... Also, there's a site dadsofdestiny .net which is for people who don't have more then an hour or so to play at a time. Usually you can one or two parts of a raid down at a time. My online time has dropped significantly since becoming a dad, I need the option to pause in the middle of playing so I'm restricted to campaigns, etc. but GTA V is great for that.
