I very much enjoying playing this game: being both a huge star wars fan and an avid MMO gamer, thank you. But, I prefer playing solo and as I now have high level characters, I can reflect back and express my personal opinion- that there are way too many Flashpoints and Heroic Missions that require a group, which interrups my personal style of gameplay.
And? Noone forces you to do them. Please continue playing solo if you like it instead of trolling the forums.
