I wouldn't go as for as 10 minutes, but there has been the case where the server will be high in activity and due to both the ct side and the t side maybe causing problems by delaying the round through talking too much, or rebelling can cause the round to end without much happening. There has been plenty of times as when I was say hosting a death game and the timer would cut me off before every t has gotten a chance to participate. Usually that happens because people on both sides keep talking causing others not being able to hear, or people taking too long to react. Overall I wouldn't mind the time being increased but not much because sometimes people will get tired of waiting a long periods of time to be able to enjoy the next round.
