But the top handguns you can get on each team (deagle and dual elites) are far better than the cheapest SMGs (TMP and Mac 10). Pistol rounds are usually over so quickly that it's pointless reducing the buy time. Sure, they could have an automatic weapon late in the round, but chances are they would be on lower health anyway. Deagle headshot will pretty much solve all your problems. I can't see it being a challenge, really. I agree with keeping it as it is, it's really not that much of a big deal.

Also I am one of those people that buys the automatic weapons late in the round, and I don't want that to stop because that's how I get all my kills for the entire duration of the map
