It is NOt logical. Your Trooper is a REPUBLIC soldier. It has a storyline. Defecting to the Empire would not work at all. You want to switch sides? Play a BH. But faction changing in this game would not work. It would ruin the game.
You wrong.. money is stronger than the stupid saga of star wars.. I call it personally stupid because it is not an actual invention, but a disterbed ancient mythology.. story. Very well camouflaged and a good movie to spend ur time..
anyway... Blizz didnt followed the story line also, they made it vanilla and u can play as a kung fu panda, even if the worlds are the most beautiful, game is over I believe.. Everybody excpects TITAN.. then next one.. But blizz allready said is going to be EXTRA DUPER SUPER casual mmo... If they dont add tokens again.. and its mostly world content, i may buy it.
What makes you believe, that you will not be able to do anything in swtor for money in the near feature..
After all, its good to be able change sides with my current role.. lets say that "i am a sold out soldier". or " a jedi who followed the dark paths" ... They have the light and dark faction, but only for items, they could use it for other things to..
It would be great to do it, but they must add a couple of planets, so the deserters move there..
