The breaking down of the jail gates is good but certainly needs tweaking. I really do love the rush it builds and makes me really want to go for the flag.
The floor switch doesnt do much for solo attackers. This is based of my own experience so far. If I'm by myself, I have to sort of invite or gain the attention of two other players to the platform, which doesnt usually get a quick response or none at all.
The situation sort of ends up to be a bit odd because I then end up pking those same players soon after the switch has been set or vice versa. It's like, "thanks for your help, now prepare to be sword spammed to death!"
