If you're going to play SWTOR you might as well just play WoW, I don't think many people play SWTOR anymore or any of those 'WoW killers'...
They do a thing now called Flex raiding or something (I don't slay magical puffy dragons, I PvP) where you can just queue up solo into a group of 25 and do the raids on a lower difficulty allowing you to see all the content. It was designed for those that can't fit a certain schedule or don't like 4 hour slogs etc etc.
