I was the same as you but they went through the scenarios we had for them!! Its emotion and human error, that's what they put it down to. I don't believe it is scripted anymore. The developers were saying it is the most frustrating thing they hear about the game!
Tom, I cant give too much away...
We went through this with the developers, it is not scripted. We went through about 25 scenarios when playing FIFA 16 vs CPU and user to which we all analysed with the developers to prove it is not scripted. Human emotion is the key here!
There was one guy that said he ALWAYS concedes a goal...
I was play testing FIFA 16 couple weeks ago, trying the new games features at EA in Guildford! They have made some really good additions for the next game!
