Ask EA Phenomic what happened when they did the same thing when they hit their 'Milestones' in number of likes, they gave a very limited code and went from 75k likes on facebook to barely pushing 60k in a matter of hours. Now when they give codes, they are unlimited uses, 1 per account.
As a celebration, all active accounts either sub or not should of automatically been given 450 Cartel Coins, instead of "Here is a limited use code"
Sorry, to maintain my subscription I have to go to work, like everyone else. I think it might be time I reconsider my subscription, and as a returning Founder, with the CE Edition, leaving this game again is not a hard decision to make.
Smarten up Bioware and EA. Do things right, and you might be able to convince myself and possibly several others to keep and/or renew our subscriptions when the time comes.
