Sorry to be a pedant but, as I used to work in retail, that's not strictly true. You are only entitled to a refund if the goods aren't fit for the purpose for which they were sold. Credit is up to the individual retailer.
Apologies but it's something that is far too often misinterpretated.
I was thinking of DSR, and some stores such as Argos in the UK where you can take stuff back even though you opened the box and tried it.
Anyway, with any game change I always ask myself 'is it fun?' and 'is it necessary?' If it is, then great I'm behind it 100%. In this particular aspect I love everything in the power play game. 99% of it is both fun and necessary so big thumbs up.
Now, maybe we should just shut up about the 1% we don't like, but to my mind the purpose of feedback in a beta test is to not just say the stuff we love, but also point out in a constructive way the stuff we don't.
So it's not whining or being ungrateful because I love 99% of the powerplay stuff and you can tell how much work has gone into it.
I just don't get how the 10% module swap fee is fun or necessary after 6 months of the game being live. That's all.
