This is nothing new for a MMORPG. First, the game is online which means that there is a certain anonymity that leads players to speak their minds more openly. Second, The game is an rpg. Rpgs reward time invested and hardcore players (the ones who speak out the most) tend to focus on a single aspect of the game. This gives them a pretty skewed perspective. They see a class do more damage/defense/support/mobility and want to know why their class doesn’t have that. They might see faster character progression in pve vs wvw and want to be able to enjoy the same progression doing what they enjoy more. Third, anytime you put a significant amount of time into something and it gets nerfed, there is generally a negative reaction.
