The jump servers I run are still on build 21 due to forced deathmatch not working on later builds. I think there will be lots of opposition to this if it means no more jump servers. I don't think I would have a problem updating them to the latest build if it works.
I don't remember the reason why I haven't updated all other servers, they are still on build 32 with oldphysics on. I am planning to keep oldphysics on so I would really have a problem with this if this idea was implemented and in a later build the option was removed. I guess you can call me stubborn for this, but changes to physics are something the majority of "veteran" players can't stand. The biggest one for me being the fact that you can't slide any more without holding space (hate this so much). Don't I have the right to be a little bit stubborn when it comes to my own servers though?
I am too tired to think of any other good reasons right now but I am pretty sure I don't like this idea, depending on what your definition of recent is and status of deathmatch bug.
Will double check tomorrow while at work though =p
