Look, your money is of the same value as everyone elses, but who is more likely to be quitting and not interested in free time? the guy that isnt lvl 50 or the guy that is lvl 50.
From my Point of view the guy at lvl 50 is more likely to stay in the game t han the none lvl 50 guy, seeing how hes come to the point of the mmo where the real addictive content is. Also if hes got a lvl 50 doesnt it give an idea that hes settled upon swtor as hi s mmo for now atleast, and would prolly keep playing?
Ofc it sounds unfair, i can even see the bias above, but i dont see the logical reason behind rewarding people that arent lvl 50 yet seeing how easy it is to get to lvl 50, even time wise it doesnt take long. So as to kinda repeat a bit of the above, the lvl 50 players have prolly played from the beginning and havent quit, thus making them more loyal costumers than you w ho invest more time into the game.
