The fact that we bought lifetime subscriptions means we're looking ahead and past the launch week, which has always been insane for MMOs and will always be insane for MMOs. In fact, we look past the first 16 months! We invested in the long-run because we expect the long-run to be worth it. Why would we judge the long-run based on the problems of a few days at the very start?
Seriously, stop worrying about the lifetime subscribers. We don't want your concern.
I echo this sentiment. I have played nearly a dozen MMO's in my life so far. I expect server crashes and queue's in the beginning, in fact I expect game crashing bugs for the first few months. I will get a good sense of what the game will be and the direction is headed into in the first 6-12 months. Me personally, I am not the gimme now type person.
