In your fantasy world people are going to be lining up to spend their hard earned ISK for your injectors. But what they will actually be doing is clicking ‘buy now’ on the shiny picture CCP keeps waving in their face.
Like this one:
CCP removes thinking from the adding SP equation. You think you can beat that with your little diagram in a forum only twenty five people regularly read?
Sure, but I don’t care about those people; I care about me.
Also the trading volume for injectors is pretty high, so someone’s definitely buying them.
Also, only a small fraction of F2P players buy anything for cash at all. Meanwhile, quite a few free players might buy injectors for ISK. There’s a huge secondary market for these items, and stacking discounted, long-term subs on top of offers like these lets me subscribe multiple accounts for the equivalent of like $5 per month through SP farming.
