I think Double EXP passive is not necessary (for people that link grind like me it's not a must have, event without we can finish most part of the current game)
Double Item drop hum... Why not ? As battle passive ^^ (On a character like Nazrin then)
Sell-High : Can be a item I think, with a subquest.
Haggle seems good, but I think the same way than Sell-High.
But event without this the game is still nice ^^
I will try your new patch (I was stuck on Eientei's 2nd visit with the graphic bug that I told you on Youtube) . If it works, in my opignion, working on beta5 is better.
Well it's only my opignion, by the way i am sorry if I did faults here, english isn't mynative language and I don't want use Google crappy translation ;)
EDIT : Eientei's 2nd visit first map (whith the flash and the box that told us all taps are desactived) works now, but the second (the door in the top of the room) don't work. We have texture, but we can't move.
