I'm not saying the game is going to flop. Or WoW > SWToR. What I am saying, is saying anything like "Played 16hrs, or 2 days, and due to what I've witnessed, it will dethrone WOW" is a terrible way to go around judging and comparing these type games.
Statements like that could only even start to hold true after a few months of the game being launched. Then at least you can start to compare more, IE updates, longetivity in gameplay, customer service etc.
Also "The combat is more interesting" is an opinion, not a fact, and what are the bets some will say they prefer WoW's combat? PvP is addicting, to you, for now. Again what about in a few months? You really don't know. Also balancing issues occur in every game, and will occur in SWToR. In PvP it's only time until complaints start hitting the forums, and in PvE there's no meters to say what's actually going on.
Tl:dr Right at this moment, it's only judging a book by it's cover. This kind of book though is the type that takes months to read, then and only then can you judge.
