WHY do Square always use the random encounter system?

[Peter_20]

obviously you're not a FF fan and not all FFs have that system. XIi doesn't and you would've known that if you're an FF fan and you don't even have to play the game to know that.

I know FFXII doesn't use it, but why did Square need almost 20 years to realize they should remove random encounters?
That's inexcusable.
