Whilst you do have a point, they cannot be solely responsible for balance. Asking for input from your playerbase opens up the opportunity for a lot more feedback than any in-house testing could possibly grant. In my opinion, ArenaNet have always balance well. I have been affected by it since the early Guild Wars days and have always found it to be as fair as possible, though I am not ignorant to difficulties that come with balance. Go and main engineer, than tell how their balance is fair? Support scrapper and dps scrapper are getting slap, holosmith as been set back dps wise compare go other, now in term of good build we basically have proc holo for pvp and that more or less about it. And the worst is not even this, they dont just nerf they change fun trait with interaction, and gameplay change effect, for passiv boring one. Patch after patch the class is less and less fun to play.
