Hermana Hambrienta Menor

Hermana Hambrienta Menor
Clan: Blood Brother (group 4)
Capacity: 2
Disciplines: pot san
Sabbat. Mexico City Circle: Hermanas are not unique. When moved to the ready region in your influence phase, this vampire burns 2 blood or is burned.

Can you influence them into play with 3 blood then burn 2 blood as they come into play leaving them with 1 blood?

No. If you have more counter on a vampire than his or her capacity you must burn the excess when that vampire leave unready region

Sorry for my english.

For reference, this was confirmed by LSJ here

So the card should say "After being moved to the ready region in your influence phase, this vampire burns 2 blood or is burned". The way the card is currently worded makes it seem like you can choose the order of draining the excess blood and burning 2 blood.
