I agree the story is a suspect. If Lightning wasn't a hotrogen this game would have been a lost. Lol!
The MMO type random drop system just made collecting stuff and gaining money a chore.
Needing to beat the game 1st to finally max out your crystarium made most of the high level side quest impossible to finish on the 1st playthrough. I can't remember an FF game that I couldn't do all the side quest in one go, except for special dungeons that only appears after beating the game.
Aside from those, I never actually had an issue with its linearity and combat system (well except the part where you cannot control the movement of your main character in combat and if your lead dies its game over)
