A completely new battle system(one never before used in an FF) does show the lack of ideas. So does a brand new magic system, new characters, and a new story.

Seriously, though, Square works night and day(literally) to give new things to the fans. We get a new and more action-oriented battle system, yet Square's suddenly running out of ideas because they're using a name from one of the previous games? They've been using Biggs and Wedge for God knows how long. OH CRAP! Square must have been running out of ideas for a damn long time. Damn you to hell, Square!
