Personally I would go for improvements. We have the old game for the old stuff, but now we have a chance to improve things a bit. There is no harm in a fixed teamchat. While new players may not know/care about it, it can definitely cheer up players, who know they are playing on a fixed dedicated server. I'm not sure what benefits/drawbacks it might bring, but the trigger system is to be discussed in detail tho. If nothing else, we can at least have the user choose what fixes the server should run.
