Okay no.
Its a difference between changing a few numbers in the code and calling it "updating" thus breaking the gamemode making it a shadow of what it was intended to be as opposed to actually adding something to the game itself (i.e. new traits, melees, maybe custom zombies) that actually compliment the gamemode and make it feel fresh. People are complaining because you rigged the gamemode and called it "updating". If you just added some melees, traits, or a few guns and maps, I can guarantee you would not be facing this much backlash. Updates add something fresh, you added nothing but a minor inconvenience to seasoned players.
However Kigen fixed it and actually listened to what the players had to say, so good look there.
