It happens every time a game tries to do pve and pvp. Look at wow or rift or swtor. Basically any mmo (we can argue this isn't a pure mmo but it certainly shares the core ideas) the pve or pvp experience always suffer because people get vocal about hard to counter items...some of which should be corrected but once a community realizes the devs actually act on feedback they get even more petty and vocal and the game slowly becomes this unrecognizable shell of what it was.
