Simple as in 1v1 and dribbling? Yes, I use very simple moves like a touch inside then accelerating outwards, or simple rolls, cuts and occasionally scissors. I dribble when there are few or no good passing options and few defenders around me. I can be very simple going 1v1 where I just use my brain to outsmart the defender rather than complex moves. There's really no right answer, it's just so dependent on the situation and what's at stake. If you want to try something, go for it. But is it really worth the extra glory if you're only getting by your defender 2 times out of 10 instead of 8 or 9 times out of 10?
Simple as in passing? I really can't say. I usually only pass short quick passes when I'm doing stuff like wall passes, takeovers, and other more complex styles of play. I'm not saying I never pass the ball short, but I usually take a really risky through ball that curves around or lobs over the defense and usually puts my player on a 1v1 with the goalie. Say I do this 5 or 6 times a game, and it works 3 or 4 times. Well, that usually turns into 2 or 3 assists. When through balls aren't an option, I either give it to the CM to distribute, pass it off to a winger, or, most commonly, dribble it near the goal and either cross it or shoot. I don't know if you would call this simple, but I would definately say it has some of the "trick" factor involved.
Overall, I keep it simple soccer. I do what I have to do, and I only take risks that would end up with scoring chances. I don't take risks to give myself glory, because I see that as selfish if you do it too much. So if anyone here plays "tricky" soccer just for the sake of doing moves for your own glory, think about if you're still contributing as much as you could be with a simple style of play. If you are, great. If not, consider some changes; you could become a better player.
