mattdy: things like drop speed and turning speed can be controlled through the script, so we can change them if people find them particularly annoying. we do already have code in place to keep the teams balanced (the same code used in the samp version) though it has not been thoroughly tested, if there are any specific situations you think its wrong in let us know
uhm: telling people things about the game on-screen seems to be largely a waste of time, people dont even seem to read the small messages shown when they spawn (/reclass to change, etc) let alone the text at the spawn screen or some map specific functionality (like not driving on desert)
there are a lot of potential problems with player count specific real time changes to the game, first we have to decide where to draw the line; if we do give people different weapons, what happens when the player count increases again? removing or swapping weapons in the middle of a fight would annoy everyone (similarly, if you are in the middle of a fight and the player count drops). if you're in a car, swapping that out if the player count increases while you are driving is obviously not practical, and adding/removing spawns on the fly would just cause confusion. this only really works with heavy weapons because they are disabled completely, though some of these problems are also already seen with them (and actually should probably be fixed if we can think of a way to)
