Except that buying another BFA doesn’t get you anything for your current account… Buying a boost does. And people pay for it so… why would they change it? Especially when it’s a limited commodity.
I mean theoretically people could buy 20 faction changes for a single character depending on how they’re feeling. I think i’ve bought 15 or so (faction changes) over the last few years personally. However, optimistically, people will only buy 12 character level boosts… or 11 if they bought BFA and got one for free. Most will buy much less, but they wouldn’t be 60 bucks if people didn’t shell out the cash for it.
Edit: Not to sound rude, but I did notice in another thread that you are rather young. The perception of it may have to do with your personal view on the value of money as well.
