Did XII allow you to dodge by staying back? I can't really remember. Seemed like it did what XIV does: if you can stay out of the red AoE fields, you can dodge big attacks. But for normal attacks, it doesn't matter if you're in front, behind, or beside them, you will be hit.
I think we've come far enough in RPGS where we have the big staples:
-RPGs are now real-time,
-they allow input for AI (Tales games have always done it, and XII developers did indeed give players the entire programming table with gambits.)
And I think if they really take back what Square had going for Mario RPG, i.e., Timed Attacks (and naturally from there, Chaining), that would alleviate people's fears about the one-button presses for attacking and dodging. The Mario&Luigi games really punished you if you didn't have the timing down.
That's why I never really understood why Squall was the only one in FFVIII who had any timed attack mechanic. For just one ability even.
