i never swap teams because like to stay with the people from the last round
and thats how you create freinds my dear people stick with the people who are in the same squad(theyll likely create that squad again next round)
theres no need to swap teams to help out another,its likely that theyll have some one experienced on their side.
and theyll form up maybe, generally their side is losing due to a lack of teamwork, and you aint gona change that, one person cant take on a whole side.
anyway if your new to the game you should join the other side, i had some random dude who wouldnt join the insurgents even though he asked me to teach him(he should therfore not be complaining and asking to be taught in the first place)
