See, I disagree that the soundtrack is 'bad'. For the most part, it isn't stand out, and if you think that the music should COMPETE for your attention in a game, then this is not a soundtrack for you.
But there is a belief in composition that states that rather than competeing for your attention, the music should accentuate the scenes, and the music in FFXII does that perfectly.
What we have here more than anything is an argument between the two prevailing views of how you write music to scenes. Both views are valid, and both work.
