There are one or two things that I agree with on that list, but one thing I simply cannot agree with is the Eidolon comment.

*The useless and uninteresting Eidelons. They feel tacked on. Whereas FF8 made them a big part of gameplay, in FF9 they revert back to FF7 mode and become what is, essentially, an uninteresting and overly magic spell
They most certainly do not feel tacked on. While FF8 may have made them a big part of the gameplay, (which it didn't. They were useless and the easily abused Junction system made them useless far quicker than FFIX's Eidolons became useless) FFIX's Eidolons were made the main focus of the story for quite some time. The majority of Disc 2 is about Eidolons, extracting the Eidolons, Odin destroying Cleyra, Atomos destroying Lindblum, Garnet recieving Ramuh, Bahamut at the Iifa Tree, etc. Sorry for the rant, but this comment just annoyed me the most out of all of them.
