In my opinion:
About removing the jail, well this is a classic surf server, not a death match, and in the classic surf servers the jail is a part of it, if you say that the new players will not learn how to surf, well I played surf here in ambrosia before 4 years, and I knew how to surf even with a jail, why? because when I know there is a jail, I do my best to NOT fall down, meanwhile if there isn't a jail, my focusing in the surfing will be low, and I will not care if I felled down, also, if I am surfing and a random player is following me with a shotgun, you know what will I do? since there is no jail I will fall down and escape from him, so for removing the jail part, I disagree.
About making the surf server a death match, well honestly, if its going to be death match, I will stop playing there, because its really boring, I played in a lot of death match servers, the number of the players who don't know how to surf, is just too much, most of the players are camping especially in the spawns, just to get more kills = more ranks, and it will never teach you how to surf, in death match ur focusing will be on the kills, that is ur objective, getting more kills. In the classic surf server the objective is to NOT fall down in the jail.
About the delaying part, that's why I suggested to force the round to end at 0:00, well at least this is a good way to stop the delays.
