I kind of agree, since the auto team balance was introduced the quality of team work has dropped a lot and I dunno if it's just me that gets auto assigned to a certain player type but when I was playing last night we had about 6 medics, 5 engineers, 1 demoman and 3 snipers and it was crap because no one was trying to get to the next point.
Noobs joining the server can't be helped though but it does get quite frustrating when for example you have a noob medic standing right next to you and your calling for a medic and your not healed but not much you can do about that as we were all noobs once
Alltalk definatly needs to be turned off as I don't want to say anything on mic now incase the other team can hear me.
Also I dunno if it's just me that hates that cp_stag_b4 map, on paper it looks very good but its very poorly layed out and realy confusing to navigate around. The few times I've played it on fm tf2 server most people have been moaning about it and typing rtv so It can't just be me that dislikes it. Perhaps remove it for now?
