The only time I used them was during the tutorial at the beginning of the game. They seemed hard to use so I've been using non-motion controls ever since
I played Splatoon ever since the first Testfire, and Motion Controls were turned on. At first, I thought it was really weird because I always had the thought it would be like most shooters. Since I didn't saw an options button, I just sticked with the motion controls. Then I found out that they weren't that bad. Finally, I found an option to disable motion controls and so I did. Splatoon is nearly unplayable without Motion Controls.
I'm happy that I never found the options button at first because if I did, I wouldn't win as much as now.
It's thanks to Motion Controls that I win almost every Splatoon match.
I use motion controls... I can turn them of with a roller (I don't like to, but it is doable) but I don't see how people could turn motion controls of with a gun...
My friend doesn't use motion controls and I think he's crazy..
