Hi,
While it can be annoying, it isn't actually impacting the time as the initial openday is purely to let players download the map, load in, and check the map out. CTs are still expected to end it with a reasonable amount of time, and getting guns via gunroom is not a requirement.
Enforcing a rule like this would be messy, and ultimately provide little to no gain for the effort of policing it.
