For the love of god, learn to play and stop being selfish idiots. The jungle is not designed for 5 people to farm it at once! What's worse is you noobs that start with the jungle item, AND NEVER UPGRADE IT! Or the other noobs that refuse to defend or push a lane, and just keep wandering around the jungle, even when your max level (and omfg if I see a full build with a t1 jungle item, @ lvl 18 and over 13k gold, ignoring the lanes, I want to explode your head with the power of my mind!).
Jungle play is designed so one or 2 players on your team can forgo lane experience and gold, while watching the map for ganking opportunities and defensive needs. It is how a team maximizes their growth. Essentially 1/4 of the jungle = 2 creep waves and takes about 90seconds to respawn. So it's slower growth then lanes are! Also, ignoring creep waves is ignoring experience and gold. If you're the type of moron that will completely ignore protecting a lane turret, so you can try to out jungle your own team, you dont deserve to win! And if your whole team is jungling, just delete the game now, because you are the idiots that lose while having more kills.
Pushers are not junglers, Support are not junglers, Tanks are not junglers. Gank (fighter and assassin build) are junglers!
