The main thing about the Lire revamp is the HUGE xbow change.
Mainly that even though the bolts come out a lot faster/more accurate, the damage has also been reduced, and you can't stun monsters anymore, so no more edge-of-the-screen spamming. The harpy ... I don't know. The damage is great, and I can usually fire it off with 80% accuracy unless a party member does something stupid. It's also unique. But they've replaced it with a Dragon Slash wannabe, so I'd have to play it to see how much better it is. Don't remember the other specific changes. @.@
I love the pictures--that's a definite plus.
