Lol. I don't get AAA'ed when I know what I'm doing. That's why there is BoF -->w/e, EB or DD, and other characters like Maria with PB and SB, etc.
I do love SO3's battle system much more than the SO4 one, but from personal opinion, and what others (people, forums, reviewers, w/e) have mentioned, the battle system isn't as bad as what you think. You're just one of those people who don't like it, but hey, that's preference, and I don't mind that. It's not bad that you think what you think, but you're tone just sounds like you are bashing something widely considered to be good. I don't have a word for it, lol.
I say this because the battle system is what brought the excitement to this game, which is probably the only reason why it gets good feedback, other than probably music and graphics (which is most likely to a very small minimum). The story was lackluster, to the point that I could just skip everything and still get what the plot was about. It has been mentioned that the battle system is what kept players into the game more and more, and nothing much else.
Basically, the battle system made the game what it is.
w/e. Yeah, SO3's IC was so horrible. I spent countless hours on something that could be easily done in 2/4.
