Blocking doors in Ctf is usual, but players like Caleb and unfortunately many other abuse that, to trap players in certain rooms, such as the 2nd floor of the "Flower" house and the Healroom under the Bridge. Those players are being kept in there and can't get out because the exit is being blocked, so Players are able to get in, but not out.

You may ask how those players lure others in there? It's simple, by saying "There's a free ec" or like caleb did, by saying a staff is abusing his/her powers 'there'.

I hope you can somehow stop this, so that a Team wont lose so unfair like this.
