I just went to give a fellow guild member some MK-11 Augmentation Kits (10 of them) and when I traded, it cost "me" 5,050,000 in credits. Really? I am helping a fellow guildie!
I did not mind the quick travel charges, or leaving the guild ship parked over the Gree event, and I would not mind you charging a little bit more for putting things on the GTN at ridiculous prices, however...
Sending Conquest Reward credits to the top ten in guild each week, trading with guild members needing something from the guild bank or handing some credits to a guild member is ludicrous (ridiculously absurd).
I am asking that you take a step back and please, re-evaluate what you have done. It is like the real world economy, you are making it where playing the game costs more credits than the "real money" we put into our subscription payment.
But then, if you want people to stop paying for subscriptions and allow the game to die a death of natural causes... it is one way to move staff to games that make you money.
