So there are people who use SWAT 24/7 instead of going regular cop when SWAT gear is not needed. I believe that's a problem as what you end up with are people getting mowed down by M60s whether their heat is 1 or 999.
I think there should be a way to limit the usage of SWAT in such cases, as it really gets annoying for the people who try to, for example, roleplay a chase but instead get killed in the first 15 seconds. My suggestion would be to make SWAT available only when someone has a high enough heat level, or when there's a mass RP going on, in which case it would be allowed by an admin.
This doesn't happen that often, but better defuse the bomb with 2 minutes rather than 2 seconds left, eh?
