I think it is mostly a community issue in MMOs. There are a lot people that have the mentality that you should be only maxing you DPS output as a dps. Most people really don't consider party support. If you need them to do something I would suggest just asking. As a Nin there are times that I forget to goad because I am focused on my rotation. A simple reminder from the tank helps pull me away from the "max out my damage" mentality and into a support my party one.
