It's been this way for years, I don't see this changing.
If an admin switches a player to CT and they break rules, they will be punished like any other player.
Even if you have never played CT, you should know the rules of the server.
I understand where you come from but the ratio 2:1 is set for a reason.
I've played when its 3-4 CT's Vs 8 T's or more, It becomes an issue when the T's overpower the Ct's within the first few minutes due to lack of CT's.
The way Fuze explained is the best way of dealing with Ratio.
When I was SA I would ask if anyone would like to go to CT and if no one went I would switch the highest Kill count T to CT.
Rinse and repeat.
I also do not want Gangs to go away, I think its a great idea for T's to work together officially rather than just by using a tag.
As for CT's I'm sure they can think of something that is similar to T's Gangs.
