This is because privileges were taken from fans and players, and given only to those who paid.
The game uses a P2P networking system, so there is tons of lag for many players with slower connections, unlike Counter-Strike.
It has a fair number of weapons, though the ones which free players may use are either expensive in-game,or were nerfed down.
The game has fallen back as the best FPS because of commercial release. Updates are unreliable, and so are servers. Often, the game is easily hacked, because of using a really bad anticheat, Punkbuster
Guy2: You fail at life, go play some real FPS like Counter strike: Source
Person 2: Why? So I can get bitched at by some child who claims I'm a hacker since I shoot him in the head for hiding in the same spot?
Lately the game has been going downhill, hackers have overrun the game, and PunkBuster is unable to stop them as they can bypass even hardware bans. Not to mention the game is filled with 10 year old prepubescent nerds who lack brains and/or language speaking skills.
