Eh, the battle system in XII was... okay.
Problem was, they tuned the entire game ludicrously easy, to an almost nonsensical point, because they were afraid people would freak out over having to move their characters in the field...
Which led the game to be so easy, that your gambit run allies can easily solo anything up to around 10 levels higher than you. And only stuff around 30 levels higher than you was reasonably difficult when you joined the fight.
That's... bad D:
Even setting that aside, after four years of FFXI, FFXII played entirely too similarly for me. I felt like I was playing FFXI where I had two NPCs with AI instead of actual players. It actually might have been a lot more fun if you could just play it multiplayer. And it was yet another game where all the characters were generic in gameplay terms (except for oddly, Fran and Balthier apparently had penalties with the bow and gun respectively... wtf?)
One of the problems with it, and I think this is a major problem with FFXI as well, is that after you inevitably get the relatively simple strategies fleshed out, the only thing to really enjoy are the action elements, which are scarce.
I enjoyed X-2. At least I liked it better than XII, not that that's a great compliment.
Ok, now we're going to get slash fiction of Wint x Kachi somehere... rule 34 and all...
Never confuse your inference as the listener for an implication of the speaker.
Good games are subjective like good food is subjective. You're not going to seriously tell me that there's not a psychological basis for why pizza is great and lutefisk is revolting. The thing about subjectivity is that, as subjects go, humans actually have a great deal in common.
