If you have looked at this game but been on the fence about it I would recomend picking up a package now if you want to test it as it is being developed. They are down to 377 left right now and had 900+ yesterday. You can get a package for $40 bucks that includes alpha access and will be much cheaper than the finished game at release.
Here is a video of the upcoming dogfighting module to wet your appetite. Note the stream is long because it is the whole stream, even the questions at opening and the demos. You can fast forward to the actual footage if you don't want to see the interview questions.
I don't really see that at all Cell. Sure if you have a lot of time you will have more stuff because you are doing more but there is no reason to think you can't just play casualy and have fun doing your thing.
In Wildstar initially the factions start on their own continents. Then after I think the first two they meet up. I haven't gotten over level 15 but I do know at 20 it is possible for exile to visit the dominion dungeon and vice versa.
... once again ... waiting on EA to reset my password ... so I can play a game I bought ... I hate Origin... :-( (sorry Cell but it's the truth... 3 hrs.. no password reset.. waiting 40 minutes for "contact us" = BS)
