No Haurchefant and Ysayle?

[MsQi]

I very much look forward to this event where we can transform into npcs! However, last year, they did not include Haurchefant nor Ysayle, and this year they did not include them again! Why is that?

I don't know if it's a cultural thing,

but they don't seem to let you be anyone who is dead.
