If you end up liking SWTOR and you find it very similar to WoW, but it's nothing too different....but it's enough to make you use SWTOR as a time-killer instead of WOW....Do you think you'll go back to WoW and try it's latest expansion even if you're spending all your time enjoying SWTOR? So pretty much....would you drop what you're doing in SWTOR even though you're enjoying it and you've replaced it for WoW and pretty much not logged in WoW since playing SWTOR.
If you're one of the people who are going to try SWTOR please make a comment, if not...no real point hey!
