So, I just found a thread with some interesting «information» about FIFA points here. Decided I had to try it, but it didn’t work for me. When I went back to read the thread it was gone.
EA opererates pretty much like dictators - both on these forums and with their customer service in general.
The decent thing to do in this case would be to have a representative comment in the thread and explain that they knew about the issue and that they were working on it (and that they had disabled purchasing packs with FIFA points until the matter was resolved.
The thread I’m talking about claimed that it was possible to buy packs with FIFA points, then go the dashboard and quit FIFA during pack animation - and to receive the contents of the opened pack whilst NOT be deducted FIFA points.
