1 sounds good in theory but not so much in practice. This class gets a nice little story arc while the rest have to sit there and labor through dailies and air grievances on the forums. Also, if you're going to do that, you'd need to commit to it for the entire process otherwise a number of classes are going to be deprived of comparable content. Also, how would class-specific content work at this point, given that, for all intents and purposes, all 8 characters died on Darth Marr's flagship?
For 2, are you talking about something like Makeb, where each faction had its own story arc regarding an event, or something else?
