I don't want to spend (and I don't want my players spending) any more time thinking how can get every possible + to get a better critical.
It's the same as thinking about how I can raise my general attack -- sorry if I made it seem it was something different. It basically means that even if you are pretty certain to hit (or be hit) it's worth thinking about improving the odds in your favor. If you don't want to spend time thinking about how to improve your odds, then PF in general is probably not a great choice as it's pretty focused on tactical combat.
