its true, when you are in a league game its best to hang around until you can exit with honour...BUT, it does no good to your team if you get shot down because you are a cripple and didnt try to get away

some players will try to bluff you and imitate a glider so you do have to watch for those...rather like a stall...if it works it was a great move, if it doesnt...well what were you thinking

some of the players are talking about team play...
about how only one player wins in the game...that is completely true because of the victory conditions of the game...in my opinion its something of a flaw and should be addressed...a team victory should be seen as that and the victory given to all of the team members who survive

in the last analysis...everything will depend on the situation...if you are isolated from the fight, hanging around is not a big risk and it is best to do so...but if there is an enemy with his nose to you and closing, then its time to go
