As far as I understand the rules the way multiple defenders work is by collectively deciding which cards to put in the development stack. Yes you first divide the available cards between the players and then each player places a part of the stack - but essentially this means the defenders build their stack together.
Am I reading this right? If so this sounds really bad. And why can 4 people emulate a single defender Player but not multiple people emulate the attacker?
I have another questions. How does the combat flow work with multiple defenders? The attacker plays an action card and a defender plays one next, and then the attacker. Or the attacker play a action card and then each defender plays one.
