Not really. They all seem like legitimate complaints to me, even if I don't agree with all of them. Why would you go out of your way to junction poorly? Just because it's technically possible in a lot of these cases to overcome the problem of the complaint doesn't mean it's not a legitimate complaint. Yes, you can play FF2 without hitting yourself, but leveling is generally slow and unreliable if you just play as you would any other FF game. Could you make Cloud a white mage? Maybe, with great difficulty, and probably not early on, because you wouldn't have enough white mage type materia, and even then he'd be a badass with a sword who could pretty much attack his way around most obstacles. Does FFXII play itself? Honestly, not as well as it probably should (I've mentioned my complaints about available gambits frequently before), but choosing each character's action, if not impossible, at least definitely comes with the cost of lost time of canceled actions leading to suboptimal play.

What it comes down to is the complaints are directed to the natural playstyle that comes out of the systems as they were created. The workarounds are possible, but they take dedication to working around the natural flow of play. Just because you can do something doesn't make it illegitimate to complain about unbalanced design.
