Or, you know, you could actually put some effort into controlling at least one character. I always kept Vaan with Gambits turned off so I had someone to control at all times. Honestly, the only people I ever see claim the battle system was boring did what you did and let the game play for them. If you were bored by that then you have no one to blame but yourself since the game gave you the option to not do that.
As for the most boring FF, it was hands down FFI. It doesn't hold up today at all. The story is crap, the battle system is utterly basic, and the battles themselves are too numerous and not the least bit entertaining to me.
