Trading premium imo is not exploitation per se- The big hole in the system was the fact that the premium could be bought with the weekly free gems as well- meaning a multitude of smurf acounts could yield plenty of premium- Probably the sheer amount of star coin influx at the time didn;t help either, it means people can sell on their star coin premium
A mechanism for premium days to be traded in game (only from store bought gems or vouchers) would be great - both for the playerbase and for BB as more players would find access to premium (as they would not buy gems whatever) and BB sells more gems to people willing to spend the money on the game
The fact that are differences bewteen player/playergroups is nothing new- Try joining WOW now- i bet you would be back of the line with many a thing and won;t be keeping up with the joneses for a loooong time and catching up with the top would be impossible. If you join a game late- you will be missing out on some things as it is already history- don;t expect gaming companies to adress those differences and give you a cheap or free ride to catch up with the pack
I don't recall BB revealing how they was exploited, just that they was withdrawn because of it. Given the short period they was available no smurf accounts could have been created to use in the manner you suggest, that's not to say existing smurf accounts could have been used in this manner but we will never know for a fact if they was.
That they was exploited appears to be the reason why BB has not repeated the experiment.
Your missing my point entirely. Without luxury items there is nothing to entice those who pay their way through a game. By making said luxury items commonplace you kill the revinue stream that BB demands to keep the game running. I was just pointing out Premiums are such a luxury item.
