It is not strictly true that it will never come up again. I've been berated by Darth Baras for my choices in the Sith Warrior story line. I've received emails from people I chose not to kill. Are the differences earth shaking? Probably not, but they are there. The story is the only reason I'm playing alts at all at this point.
I'm pretty sure that not everyone will be skipping dialogue in a month. Just those with a short attention span (which unfortunately is a good percentage of the population).
Are there issues with the game? There sure are: the UI sucks, there is no usable LFG or LFD for those that want it, key binds and UI changes can't be saved and loaded between characters, crafting is woefully unbalanced, I get disconnected from the server (by the server) and then put into a queue to get back on... etc...., etc....
The story is not an issue with the game. The story IS the game.
