Oh, I don't mean to just single out FFVII on the issue. As I mention in the FFVI thread, most of the bad trends with game balanced started with that game and if you want to get technical were also seen way back in FFII (although FFII's ridiculous mechanics make that game insane anyway). FFVII isn't the pinicle of broken gameplay in FF games either; that dubious distinction would probably go to FFVIII.

That being said, while there are certainly easy enough to break FFV if you learn all the right abilities (even more so then what that video showed) you still have to put more thought into coming up with the best combination when you only have one job and one class ability to work with. Such planing is absent in FFVII because you can equip so much powerful materia at once, with a lot of said powerful materia being practically handed to you as the game progresses.
