Would be nice if the rules suggested that you should give people who have had guns planted on them a chance (the CTs cannot plant guns rule doesn't cover it, considering that a T could plant it, or you might accidentally pick it up, or might have to pick it up to follow an order)
There also needs to be a rule that not only stops guards giving the same orders round after round, but stops guards camping certain spots round after round...
It's not against the rules, but I think saying "No camping" doesn't particularly work either. There needs to be some medium where CTs cannot camp spots which lead to Ts being forced to do nothing or face near to certain death when confronting the CTs, and allowing CTs to not be forced to go into situations where Ts can easily use their greater numbers to win.
Prison Break doesn't really allow for perfection all the time though, so I think that it needs to be down to admin discretion, but admins found abusing this discretion should be punished.
