Game with high frustration factor

I played WOT (World of Tanks) 15,000 games long, initially in the belief that one could actually "cause" anything. But over time, and deeper insight into the mechanisms Games was the "magic" faded quickly. The so-called "match-maker" who asks the two teams of 15 players each together, allegedly considered only the vehicle levels (+ - 2 steps).
However, it is incredible, even unlikely often before, that one of the teams is hopelessly inferior and very quickly 0,1,2,3 end the matches to 15.
With me est was indeed so, when I often won in one day, followed promptly the next day a losing streak (no matter how well you played himself) who last looked so ridiculously phony that gave the impression that it does not go with above board.
The "vision system" is guided by the nebulous "camouflage system" absurdity and when I read that there should be even different "airtight" in the portfolios (although WG repeatedly emphasized, WOT is not a simulation), it then has been enough and the game has been deleted from the PC.
Add to this a very unfriendly (exceptions prove the rule) community in oficial WOT forum where players often skeptical nasty insults of so-called "Fanboys" have to go through. These "guardians", not easily recognized by the suffix "beta tester" under your avatar, argue that it is all correct, although they have any more insight into the "real mechanics" of the game as the other faction of the "conspirators ".
Who wants to play WOT, which was warmly recommended to do this without the use of money because it has this game way too little. Always the same card, a lot of frustration about the team composition and the rather modest game mechanics, continuous insults in-game chat and a "customer service", which does not deserve the name.
