Yaeh, the only reason people think it will be worth more is because of this:

Although, yes, you are correct, it will be starting from scratch for some people, they will eventually be placed back with the characters as they are now too. With new modification of some items, 09 Buriza's will most likely heavily overpower 1.10 Buriza's.

Anyway, how much is a Fire Charm with 40 life and a Trap Charm with 40 life worth on USEast. And Griz Full Set with 40/15 Max's in everything (11 Total)?
