I don't think there will be another game like UO where you could solo and actually be effective, most of these MMO's are group oriented and you need groups to help you move along. Basically you choose a role in SB and you play it basically, for example, I am a healer first, nuker second, but my main job is to keep everyone alive, so I don't pay attention to much more in a big battle other than the health meters of my group, and I nuke targets when everyone is healed for the moment.
