Wonko the Sane said:Sure, why not? The downside is that you land prone at the feet of the guys you just stuck daggers into. They're probably not dead, and may just punish you with AoOs when you attempt to stand.
Infact if they're small sized or larger, and assuming he's more or less directly above them, they could hit him with AoOs as he fell, because he's passing through their threatened areas during his falling movement (if you think about it 3 dimensionally).
