I honestly believe they are accounts that always have a higher chance of pulling good players than others.
I've opened countless of packs and usually get nothing. Pulled an Oblak once thats it, not a single card over 10k, nor higher rated than 84. Over theast 3 days i opened 300k worth of packa and not even a si gle billboard.
My brother however recently started playing FUT. Today he asked my to help him with his first sbc because he wasn't familiar with it. He got a 25k pack and a 35k mega pack. In his 25k pack he pulled marchisio and i was already shocked. Then he opened his mega pack and out walks 89 Kevin de Bruyne. I'm happy for him but it just seems a bit rigged.
Thoughts? Or is it all just 'random'
