I’ve said it many times before and I say it again. Pub servers are unorganized, accept it or quit playing/join a clan. It’s just silly trying to get a working team on a pub, things like that takes time and effort to practice and get working even when you are on a voice channel with your fellow clan members. To even think that it would work well on a pub is just to have too high expectations. Mainly because of two reasons, 1) people might not care because they just want to waste some time, 2) people might not agree with your way to solve a problem and 3) (I know I said 2 reasons :)) Some people just dont read messages while playing.
Take it for what it is, free play time, try to do your best as an individual player, but don’t expect anything from it and just don’t bother what happens. Just because I know a pub game will never be even close to a clan war I use pubs to practice my aim first, second depending on server working as team player.
