1) that's what spacebar is for
2) if there were enough dialogue choices that changed both story and content, it wouldnt get old at all.
That is exactly why it would get old. Space bar is not a solution because you have to wait up on other people. There is plenty of story in the current flashpoints. Not everything needs a dialog wheel. Let's also think for a moment. I for one am thankful these don't have all these dialog wheel choices. It gets old. I'm in there to experience the story a couple of times at most. After that I'm there for loot. I don't care about the story and it's annoying if you get that one guy who won't space bar and you have to wait for him.
