Looks like companions, aka pets, will be a pretty big part of the game, which seems to play on part-building. May be cool if you can shape and equip these companions as opposed to the cookie cutter ones you got in Diablo 2, for example.

Just watched the video. They said there are class-specific stories, which tells me you will be locked into a class tree from the beginning. This makes me also presume it will be level based. This makes me lose interest. While it may not be good for mass subscriptions, I find the far better MMO model is to allot a set amount of points, enable various class trees with ascending and descending point costs, and let players distribute those points however they wish as long as they meet the profession experience and prerequisites for the trees. It's called dabbling, and it makes for a much more immersive and entertaining game, more so than making all XP generic and locking someone into a set path.

I hate level-based MMOs. Hate them. Furthermore, I hate the idea that people can look at you and tell what class you are, or be able to tell what class you are by the shiny ring that flashed every time you use a particular move.

I also haven't been able to tell if there is space combat. For the games sake, I hope so, because Star Wars without space fights is pretty fruity.
