I disagree. You are wrong on most of what you said. Mainly because you just want your playstyle to dominate which would ruin zombies. Some players play for rounds some play for the storyline some play to get more kills than other players, etc
What I do agree on is the part that once you get to higher rounds it being easy in buried because of the buildables. That's why I would like to see where we could keep PaPing the weapons over and over. Which would reset the zombies health.
It would only make since because the zombies gain more health as time goes on. Well if you add more PaP to the weapon it should increase the weapon thus having affect on the zombies. This way it would balance the bank being on the map because you would have to use the points for it.
