Not that I'm hiding anything but that's literally the only reason I moved to using attacking players. I know I'm risking using players out of position every now and then when there is injuries/awols or bans in my team but every normal player these days, especially defenders and midfielders goes for pretty much 10k, and even then it's no guarantee as there's normally between 5/10 bids on them.
The majority of my Fullerians attacking players currently cost 500 credits. There's maybe 1 or 2 that cost between 1200 and 1800 .
But most other players are at least 3000 with some even 10k.
You have to wait a while before decent attacking players appear but can normally grab them for well below 3k. A much more sustainable way of playing!
