Give it a go, running straight up the field. I play NHL a lot and they also used to make you alternate going up and down but finally fixed it YEARS ago to have the option to always up. Skill moves are a lot easier for me to manage, Through balls are a lot easier to pull off.
Regardless if its for you or not, I cant imagine its a huge technical hurdle for them to have the option to always have the option to go up field. Or possible adding more adjustment to the camera. Its been awhile since I have purchased FIFA on PC but there were mods that allowed you to have more field of view options with custom camera options. But even with a modded camera you could not choose always up. I don't know if that's hard coded into the game or what.
Either way, I don't see how having more options to be a bad thing. Especially when its such a minor request that has been made by many throughout the years. But hey as long as we keep selling those UT packs who cares.
