1. Agreed
2. Yes
3. This would be helpful for players like me who want to play strategically and win the game in a unorthodox manner
4. Again would make the game more tactual and reward players for thinking with both heads xD
5. This one seems like a deliberate decision from the devs, it seemed pretty obvious to me after it happened the first time. otherwise you could cheese the game and get rid of zombies much easier. It makes the gang animations a double edged sword.
